Here's a more detailed breakdown of the current valgrind warnings
when running the wine test suite as of yesterday, with the
ntdll/heap warnings suppressed (as they will be from now on):
1 --25396-- VALGRIND INTERNAL ERROR: Valgrind received a signal
11 (SIGSEGV) - exiting
1 vex x86->IR: unhandled instruction bytes: 0xFB 0xC3 0x0 0x0
2 Source and destination overlap
3 Use of uninitialised value of size 4
4 Invalid read of size 1
4 Invalid write of size 4
4 Unhandled exception: illegal instruction
5 Unhandled exception: page fault on write
7 Unhandled exception: page fault on read
7 Invalid free() / delete / delete[]
8 Invalid write of size 1
14 Syscall param writev(vector[...]) points to uninitialised byte(s)
19 Invalid read of size 4
40 Invalid read of size 2
105 Conditional jump or move depends on uninitialised value(s)
893 X bytes are definitely lost
I think *all* the remaining invalid write errors are bogus, either
they're in GetDIBits, in a video driver, or in the stack backtracing code.
All of the remaining invalid free errors are in the oleaut32 vartype test:
Invalid free() / delete / delete[]
at notify_free (heap.c:255)
by RtlFreeHeap (heap.c:1748)
by SysFreeString (oleaut.c:194)
by test_VarBstrFromDate (vartype.c:4910)
by func_vartype (vartype.c:6276)
by run_test (test.h:535)
by main (test.h:585)
Address 0x7f0a1560 is not stack'd, malloc'd or (recently) free'd
for which I've filed
