Crashes in beta 7.48.168

UnrealIRCd-4.0.11 - irc1.unrealircd.org - no crash

InspIRCd-2.0 - irc.chatspike.net - no crash

ircd-ratbox-3.0.10 - irc.mzima.net (efnet) - no crash

charybdis-3.5.3 - irc.esper.net - crash


So I got a little clever on running the old beta versions and according to my testing:

mIRC v7.47.638 Beta
1.Item 15, https://forums.mirc.com/ubbthreads.php/topics/260026
Fixed /server password backward compatibility issue.
2.Item 22, https://forums.mirc.com/ubbthreads.php/topics/260037
Now checks if /who for that #channel is already taking place and does
not resend it if waiting for reply.
Changed to use fixed T value of 995.
Changed to allow unrecognized T results to be displayed.
3.Item 17,18,21 https://forums.mirc.com/ubbthreads.php/topics/260040
Now only updates IAL after ^event.
4.Item 22, added 'l' option to WHOX parameters. This is not used by mIRC
but may be useful to scripts that parse the numeric reply.
5.Item 27, https://forums.mirc.com/ubbthreads.php/topics/260014
Needed partial rewrite of IAL routines.
Both /ialmark and $ial().mark should work as before and be backward
compatible.
Needs testing.
6.Item 28, now faster when using just a nickname.
