Bug ID: 43395
           Summary: Wine intermittently crashes after any program
                    terminates
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Every so often, I see one of the following two outputs appear after Wine
closes:

err:ntdll:RtlLeaveCriticalSection section 0x110940 is not acquired

and

wine: Unhandled page fault on write access to 0x695de019 at address 0x7bc4f41e
(thread 0018), starting debugger...
err:seh:start_debugger Couldn't start debugger ("winedbg --auto 14 96") (1115)
Read the Wine Developers Guide on how to set up winedbg or another debugger

In the first message the section 0x110940 is constant; in the second the
address 0x7bc4f41e is constant but the written address varies.

The critical section message appears because a critical section is deleted
while owned. The critical section in question appears to be that of the
database in services.exe.

The crash address is in ntdll/heap.c:HEAP_CreateFreeBlock. It is probably being
triggered by code in RtlLeaveCriticalSection(), although it may have a
different source.
