[Patch] dlls/oleaut32/typelib.c - Via a CVS search, reverse regression to get Kazza working

[Stefan Jones]

On upgrading to Wine 20030618 I found that kazaa lite will no longer
work
and gave me the following error:

No debug information in 32bit DLL 'C:\WINDOWS\SYSTEM\SHDOCVW.DLL'
(0x71000000)
Unhandled exception: page fault on read access to 0x00000004 in 32-bit
code (0x411ed9c9).
In 32-bit mode.
0x411ed9c9 (ITypeInfo_fnGetContainingTypeLib+0x49 [typelib.c:4801] in
oleaut32.dll.so): call     *0x4(%edx)
4802          TRACE("returning ppTLib=%p", *ppTLib);
Wine-dbg>WineDbg terminated on pid a
 
using in wine.config:

[AppDefaults\\KazaaLite.kpp\\DllOverrides]
"*" = "builtin, native, so"
;"shdoclc" = "native"
"shdocvw" = "native"
"shlwapi" = "native"
"commctrl" = "native"
;"comdlg32" = "native"
 
I looked though the CVS logs and mail archives and I found the
following:

http://www.winehq.org/hypermail/wine-devel/2003/06/0414.html

and the patch below which was applied to dlls/oleaut32/typelib.c

This caused the crash, reversing it fixes the error.

please fix / apply, or I will cry!!!

anyway, how do you use winedbg, I am not thick but it refuses to do
normal gdb stuff like the run command or a backtrace! Is there a URL I
missed?
