xtrabackup.exe crashes when prepares a backup

[Aleksandr Kuzminsky]

After following string in output:
xtrabackup: starting shutdown with innodb_fast_shutdown = 1
091001 10:44:21 InnoDB: Starting shutdown...
091001 10:44:22 InnoDB: Shutdown completed; log sequence number 0 45600

xtrabackup.exe crashes. The error message:
An unhandled win32 exception occured in xtrabackup.exe[368]

Unhandled exception at 0x7c91b21a in xtrabackup.exe: 0xC0000005: Access violation writing location 0x00000010.

Confirmed the same behaviour on rev.101.

[Aleksandr Kuzminsky (akuzminsky)]

As it turned out the crash happens in innobase\os\os0sync.c at the line

EnterCriticalSection((LPCRITICAL_SECTION) fast_mutex);

of the function os_fast_mutex_lock():

void
os_fast_mutex_lock(
/*===============*/
 os_fast_mutex_t* fast_mutex) /* in: mutex to acquire */
{
#ifdef __WIN__
 EnterCriticalSection((LPCRITICAL_SECTION) fast_mutex);
#else
 pthread_mutex_lock(fast_mutex);
#endif
}

fast_mutex is not equal to NULL.

Are there some stack traces at the time?
