Bug ID: 39614
Summary: Wine initialises a Critical Section for Mutexes by
NULL instead of (void*)-1
Product: Wine
Version: 1.7.55
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ntdll
Assignee: wine-bugs at winehq.org
Reporter: EoD at xmw.de
Distribution: ---
After initialising a critical section for mutexes by using
static CRITICAL_SECTION Mutex = {(PCRITICAL_SECTION_DEBUG)-1, -1, 0, 0, 0, 0};
wine crashed in "RtlpWaitForCriticalSection()".
According to http://locklessinc.com/articles/pthreads_on_windows/ this is a
valid way of initialising the critical section. However, Wine seems to
initialize it by NULL instead of (void*)-1:
