[Bug nptl/3610] New: coredump on pthread_mutex_lock()

[sources dot redhat dot com at hovland dot cx]

There is a chance that glibc/nptl is not the cause of this, but I cannot say 
for sure. 
Note that this is glibc 2.5, not 2.4 as stated in the version field.
Thanks

Also, were there calls to pthread_mutexattr_setprotocol?
If not, this sounds like either uninitialized mutex or unitialized mutex
attribute.

pthread_mutexattr_init was not called, just *_settype. Case closed:) Thanks 
for your help.
