Crash when trying to mount broken LHA archives as disk images

Hi Toni,

I have just experienced a reproducible WinUAE 4.3.0 crash when trying to mount the "OMA.lha" archive that can currently be found in The Zone. It appears the archive is broken but WinUAE shouldn't crash in such case.
To reproduce simply mount the mentioned LHA-Archive as disk image. If more info is required, let me know.

Doesn't crash for me. It can even read disk 3 which Lha can't. Only disk 2 is unreadable.

There is not much I can do because all archivers are based on existing (very old) open source or reverse-engineered routines, for example this crash happens deep in unpack routines (out of bounds array access EDIT. which may or may not crash depending on other things) and there is no existing error checks whatsoever..

OK, I actually guessed that this would be the case but thought I'd mention the problem anyway. Thanks for the explanation.
