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@winehq.org
          Reporter: EoD@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:
