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.
