Windows 7 SP1 64-bit.

I'm running multiple beta versions of mIRC at the same time, they have the separate mirc.ini files in the same folder as the .exe. Each version has 13 connections into my ZNC on my LAN. All connections into ZNC are SSL with a self signed cert, mIRC is set to automatically accept invalid certificates.

Each beta version was started in the order they were released, with the newer versions starting a few seconds later. I don't have the older releases.

//echo -ag $os $version $beta

7 7.61 961 ; Still running, 12 hours.
7 7.61 1001 ; Crashed at 55 minutes and 25 seconds.
7 7.61 1161 ; Still running, 12 hours.
7 7.61 1242 ; Crashed at 3 hours, 29 minutes and 4 seconds.
7 7.61 1281 ; Crashed at 15 minutes and 16 seconds.


7 7.62 ; Crashed multiple times before I started debugging this.


Triggered?
7.61.1001 ; Crashed while znc was reconnecting/rejoining channels due to internet disconnect/connect?
7.61.1242 ; Crashed when joining channels?
7.61.1281 ; Crashed for unknown reasons?


7.62 ; Crashed multiple times for unknown reasons after X minutes I typed something?

Another weird thing,


7.62 from a few days ago: https://www.dropbox.com/s/m18jrg06vbye5ie/mirc-double-buttons.png

Some? of the beta versions did this before I closed out of everything and re-started the testing above. I have not been able to replicate this in the current testing session.

...


Another user has also reported only the crashing ##mirc on freenode. They are using Windows 7, 32bit, 7.62 using ZNC connected via SSL. Have not been able to get more info from the user.

Thanks for your bug report. If you run just mIRC v7.61, and no other versions at all, do you see the same issue?

Also, when did this issue begin? The earlier betas have been out for quite some time. Is it possible that this issue is due to a recent change in your scripts/DLLs/etc.?

Regarding the user that reported a crash: they will need to post a separate bug report detailing their issue, including their configuration, scripts/DLLs that they are using, whether they had an issue with v7.61, and so on, ie. the usual requirements for a bug report.

Do you have tray tips enabled? If you disable them, does that resolve the issue?

It is possible that the issue reported here regarding tray tips may be causing this, although I haven't been able to reproduce any crashes due to tray tips myself.

7.61 works fine with everything I use, never crashed. I know for a fact its not a script DLL, I've been testing all of these without any DLL's.


The older beta versions are also crashing at random.

7.61.159 crashed
7.61.367 crashed
7.61.439 crashed
7.61.817 crashed

Fault offsets are sightly different, like in the others I reported.

Tips are disabled.

Maybe openssl doing something weird since its been upgraded? I've been using SSL connections with ZNC for all my testing. Other user also said they were using ssl connections.

This might be related? Fault at ntdll.dll? https://github.com/openssl/openssl/issues/12524


Maybe something in here? I've narrowed it down to just using this code and using ssl connections with ZNC. I've been manually entering "//scon -a list -n" and other commands at random times.

Code
; perform.mrc
on *:start:{
  window -iz @peaks
  server 192.168.254.66:+10000 KindOne/freenode:<password_removed>
  server -m 192.168.254.66:+10000 KindOne/SwiftIRC:<password_removed>
  ; 11 more networks here.... 
}
on ^*:join:#:{
  if ($nick != $me) {
    if ($nick($chan,0)) && ((!$hget(peaks,$network $+ $chan)) || ($wd($hget(peaks, $network $+ $chan),1) < $nick($chan,0))) {
      hadd -m peaks $network $+ $chan $nick($chan,0) $ctime
      echo @peaks *** New Peak - $asctime - $network - $chan - $nick($chan,0)
    }
  }
  ; $calc(1 plus ...) 
  if ($nick == $me) {
    if ($nick($chan,0)) && ((!$hget(peaks,$network $+ $chan)) || ($wd($hget(peaks, $network $+ $chan),1) < $calc(1 + $nick($chan,0)))) {
      hadd -m peaks $network $+ $chan $nick($chan,0) $ctime
      echo @peaks *** New Peak - $asctime - $network - $chan - $nick($chan,0)
    }
  }
  ; else { inc %stat.joins }
}
alias wd { return $gettok($1,$2 $+ $3,32) }

raw 322:*:{
  if ($3) && ((!$hget(peaks,$network $+ $2)) || ($wd($hget(peaks, $network $+ $2),1) < $3)) {
    hadd -m peaks $network $+ $2 $3 $ctime
    echo @peaks *** New Peak - $asctime - $network - $2 - $3
  }
}


This was also in my alias tab, not sure if related to the crashing.
Code
; aliases.mrc
wd { return $gettok($1,$2 $+ $3,32) }



Right now I'm testing plain text connections with 7.61.159 and 7.62 into ZNC with only the code above.

Great. Thanks for the feedback. That narrows down the issue to the handful of changes in the first beta release, v7.61.159.

It is possible that the issue could be due to updating to a newer version of OpenSSL. Beta v7.61.159 updated to OpenSSL v1.1.1e.

That said, the issue could also be due to one of the other changes.

I am going to create several betas based on v7.61.159 to narrow down the issue further and will let you know when they are ready.

Looks like SSL is not the issue. 7.61.159 and 7.62 crashed while using only plain text connections into my ZNC. I'll try narrowing it down more.

I do not detect any crashed in the use of the new version of mIRC 7.62. I also use a ZNC connection and mIRC works perfectly.

Windows 10 Pro 1909 (OS Build 18363.959)

Can't comment on Windows 10. I've only got Windows 7.

Installed Windows 7 SP1 on a VM, I've only tested 7.62 and it crashed with the same fault/ntdll.dll message, still working on figuring out what it causing it.

I know. I commented that in Windows 10 Pro I do not detect any problems, so Khaled has more information available, but if there are problems in Windows 7 SP1, a solution will be found soon.

Thanks for your help in testing the new betas and tracking this down.

It looks like the issue is due to the recent changes in Control+Break. Control+Break was changed so that it is detected only when mIRC is active. This required a more complex combination of API calls.

So far, I have not been able to reproduce the issue in Windows 7 or Windows 10, so it looks like it triggers only in certain contexts, which is why it is intermittent.

I have made a change to Control+Break, to how the APIs are called, that seems to resolve the issue for you.

This fix will be in the next beta.
