Help with fast mutex

NTDEV
1

Hi,

In my driver under Windows NT 4, I use a fast mutex. However when I call
ExReleaseFastMutex(), I get an assertion in the debugger:

Assertion failed: (Event)->Type==NotificationEvent ||
(Event)->Type==SynchronizationEvent in objevent.c at line 380

Any help would be welcome

This could be caused by failing to initialize the fast mutex object,
overwriting the object with other stuff, or freeing the memory that
contains the object.
