shutdown with innodb-use-sys-malloc=0: assert mutex->magic_n == MUTEX_MAGIC_N,
when compiled with UNIV_SYNC_DEBUG. 
Likely a duplicate of something fixed in 5.5.

How to repeat:
innodb-use-system-malloc=0 -> workload -> shutdown, 
not 100% repeatable but happens often.

Added to change log:

The server could crash on shutdown, if started with --innodb-use-system-malloc=0.
