Valgrind errors: 893 leaks, 105 conditional depends on uninit, 63 invalid read, 12 invalid write, ...

[Dan Kegel]

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
