[Bug 10141] New: Valgrind reports heap error early in wine startup
http://bugs.winehq.org/show_bug.cgi?id=10141 Summary: Valgrind reports heap error early in wine startup Product: Wine Version: CVS/GIT Platform: Other OS/Version: other Status: NEW Severity: enhancement Priority: P2 Component: wine-misc AssignedTo: wine-bugs(a)winehq.org ReportedBy: dank(a)kegel.com Sometimes on my core 2 gutsy laptop, warn+heap make test fails in msvcrt on tests/heap.c, so I tried it under valgrind: $ cd dlls/msvcrt/tests $ WINEDEBUG=warn+heap valgrind --trace-children=yes --suppressions=$HOME/supp.txt ../../../tools/runtest -P wine -M msvcrt.dll -T ../../.. -p msvcrt_test.exe.so heap.c (where supp.txt is system dependent and optional; it just skips false positives. I'll attach mine.) Here's the first error in the output: ==12738== Invalid write of size 1 ==12738== at 0x4023894: memset (mc_replace_strmem.c:490) ==12738== by 0x43F178E: HEAP_CreateFreeBlock (heap.c:143) ==12738== by 0x43F184D: HEAP_ShrinkBlock (heap.c:567) ==12738== by 0x43F24D9: RtlAllocateHeap (heap.c:1220) ==12738== by 0x43F8FBA: load_builtin_callback (loader.c:1256) ==12738== by 0x402CABC: wine_dll_set_callback (loader.c:480) ==12738== by 0x43F61C7: __wine_process_init (loader.c:2504) ==12738== by 0x402C448: wine_init (loader.c:645) ==12738== by 0x7BF0139A: main (main.c:111) ==12738== Address 0x7F000140 is not stack'd, malloc'd or (recently) free'd Amusingly, this error happens regardless of what app you try to run, even a nonexistant one emits the same error, e.g. $ WINEDEBUG=warn+heap valgrind --trace-children=yes --suppressions=$HOME/supp.txt xyzzy Is this real, or a false positive? Maybe somebody just forgot an annotation in ntdll? -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
