Forums Bug Reports mIRC 7.22 Crashing

I've just recently purchased mIRC, But every so often it keeps crashing, the only information I have is what's shown when it crashes, Windows pops up a dialog with this information in it:

mIRC Crash Report

Do you using a clean install of mirc? or any scripts loaded?

I have used mIRC 6.22 prior to this new version, and everything worked fine, No Crash or anything.

As he asked, is this with a clean install without any scripts loaded? Scripts (DLLs, usually) are the most common cause of crashing and it doesn't matter if it worked fine in previous versions. Scripts and DLLs often need to be updated for newer versions of mIRC.

I have a clean version running now with no scripts loaded, But after a while, it still crashes.

Type the following in mIRC and report the results here:

//echo -a $version $os $md5($mircexe,2) $file($mircexe).sig $dll(0) $script(0)

Thanks for confirming your copy is clean. That said, I think that will make this harder to reproduce/get any more info on. If this is really happening on a clean copy of mIRC, I feel like you probably have corrupt data on your OS, or faulty hardware. mIRC may be slow, but it's probably one of the most stable programs I've ever used. I've actually never seen mIRC crash randomly without malicious external input (exploit) or a faulty script. Not once. In over a decade.

Are you doing anything specific around the time of the crash that might help diagnose the problem? Does it happen around a preset time after starting the client? If it's really just "random", it's more likely your OS than mIRC, I think.

Do you have an anti-virus program running? If so, try disabling it to test if this continues to happen. Your AV might be messing with the client.

maybe if I run debug mode, maybe that might shed some light on it, I'll try that and get back to you.

Note that the exception indicates that it's an "access violation", meaning mIRC tried to access invalid memory. Again, I've never seen mIRC do this on its own, so I feel like there was some external influence.

On a related note, this might help diagnose: http://www.sevenforums.com/crashes-debugging/210693-appcrash-exception-code-c0000005.html

Heed the warning about overclocking. This goes back to my point about hardware. Did you by any chance overclock your machine? OCing can have this kind of effect on programs. Some modern CPUs have automatic OC detection and will up their clocks automatically by default, check your BIOS to make sure that your CPU is running at its factory specification.

Well since it crashed the 1st time, I put it on under XPSP2 Compatibility mode, and it's not crashed since.
