Summary: Typeinfodump.exe crashes Product: Wine Version: CVS/GIT Platform: Other URL: http://www.debuginfo.com/tools/typeinfodump.html OS/Version: other Status: NEW Keywords: download, source Severity: normal Priority: P2 Component: dbghelp AssignedTo: wine-bugs@winehq.org ReportedBy: dank@kegel.com
Running typeinfodump.exe, even on a bogus file, crashes with a null pointer read. Here's part of the backtrace:
=>1 0xf7ddf2a3 (0x0033f3bc) 2 0x7e5b2e2d symt_new_function+0x6d(module=0x12614c0, compiland=0x34de9e4, name=0x0, addr=0x7b884050, size=0x28, sig_type=0x3559cd8) [/data/dkegel/wine-git/dlls/dbghelp/symbol.c:233] in dbghelp (0x0033f3fc) 3 0x7e59a122 dwarf2_parse_subprogram+0x3c2(ctx=0x33f5b4, di=0x3457ccc, compiland=<register EDI not in topmost frame>) [/data/dkegel/wine-git/dlls/dbghelp/dwarf.c:1564] in dbghelp (0x0033f4bc) ...
I've seen something like this in several other apps, but this is probably a nice bare-naked way of showing the problem.

--- Comment #1 from Dan Kegel dank@kegel.com 2008-01-16 20:08:54 --- Uh-oh. I'm seeing this on random invocations of winedbg now:

This is valgrind showing a backtrace from our own backtrace crashing?!
Invoked like this: cd dlls/comctl32 WINEDEBUG=+seh,+process ../../../tools/runtest -P wine -M comctl32.dll -T ../../.. -p comctl32_test.exe.so imagelist.c I'll attach the full log.

Assumes you have my patch to runtest to turn on valgrind.

--- Comment #4 from Eric Pouech eric.pouech@orange.fr 2008-01-19 03:19:48 --- could you try whether this also happens without valgrind ? and in any case post the +dbghelp,+sbghelp_symt trace (actually, it doesn't look like an issue with typeinfo, I successfully run it here, but rather something wrong with the dwarf info reading, or an oom condition)
TIA
