[Bug 815] - msvcrt20 and msvcrt incompatibility

http://bugs.winehq.com/show_bug.cgi?id=815 andi(a)rhlx01.fht-esslingen.de changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED ------- Additional Comments From andi(a)rhlx01.fht-esslingen.de 2002-06-21 16:22 ------- ooook, now I see what the problem is... (well, not quite, but much further) Our builtin msvcrt20 has a __getmainargs *forward* entry, which thus calls into native msvcrt __getmainargs. For some reason the program seems to call our msvcrt20 __getmainargs with new_mode set to NULL, which crashes native msvcrt, as it assumes that new_mode is *never* NULL. Can you try to find out why the program calls __getmainargs with new_mode set to NULL ? We need to know whether msvcrt20 __getmainargs can indeed be legally called with a NULL new_mode. If so, then we'd have to get rid of the forward to msvcrt __getmainargs, as native msvcrt obviously has a problem with a NULL parameter here. (IOW: we'd have to actually implement a msvcrt20 __getmainargs function that calls into msvcrt __getmainargs, with a NULL new_mode check added) DO NOT REPLY TO THIS EMAIL, BUT PLEASE POST YOUR BUG RELATED COMMENTS THROUGH THE WEB INTERFACE AVAILABLE AT <http://bugs.winehq.com/show_bug.cgi?id=815>.

http://bugs.winehq.com/show_bug.cgi?id=815 ------- Additional Comments From medbi01(a)accpac.com 2002-06-21 16:13 ------- Sorry; I wasn't clear in my description. It isn't the argv[4]; it is the thing that in the Wine copy is labelled as int *new_mode (See dlls/msvcrt/data.c:__getmainargs). According to my local disassembly following the stack dump the pointer is dereferenced without testing for null in the native version. The problem disappears as soon as the native msvcrt20 is used. The full +relay trace is 50MB but that includes the parent program. The offending process alone is only 2M. However I note that the Wine msvcrt20 is rather empty; I'm a little surprised that there were no stub warnings.

http://bugs.winehq.com/show_bug.cgi?id=815 ------- Additional Comments From andi(a)rhlx01.fht-esslingen.de 2002-06-21 16:01 ------- Hmm, sounds like there might be an argc vs. argv[] incompatibility here... Could you run --debugmsg +relay,+snoop to check whether our msvcrt20 somehow somewhere returns one argument count too many and thus the program dereferences the last non-existing (NULL) argument ?
