Bug #: 30860
Summary: HeapValidate() reports incorrect results when running
under Valgrind
Product: Wine
Version: 1.5.5
Platform: x86
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: ntdll
AssignedTo: wine-bugs at winehq.org
ReportedBy: dank at kegel.com
Classification: Unclassified
When run under Valgrind, the program
#include <windows.h>
#include <assert.h>
int WINAPI WinMain(HINSTANCE hinst, HINSTANCE hinstPrev,
LPSTR lpCmdLine, int nShowCmd)
{
assert(HeapValidate(GetProcessHeap(), 0, 0));
}
fails the assertion, and the log shows
err:heap:HEAP_ValidateInUseArena Heap 0x7f000000: free block 0x7f000138
overwritten at 0x7f000138 by 0074006e
I think heap_set_debug_flags(), HEAP_ValidateInUseArena(), and probably others
would need changes for this to work.
