pthread_mutex_lock leaking memory?

pthread_mutex_lock leaking memory?

[phuong nguyen]

Hi

I'm using 5-10-03 snapshot of pthread-win32 with MSVC 6.0 SP5. It seems
that when I init a mutex with PTHREAD_MUTEX_INITIALIZER, it would leaks
44 bytes of memory when ever I do a lock on the mutex. Any one else
encounter the same problem? Rational Purify trace the leak back to
pthread_setcanceltype.

I don't see how pthread_setcanceltype() is called through a mutex lock 
on a PTHREAD_MUTEX_INITIALIZER mutex. Also, once the mutex is first 
locked, the mutex is then like any other mutex initialised through 
pthread_mutex_init().

Can you send a short code fragment that demonstrates the leak? Also, 
some information on how you're running the library if it's unusual 
(static linked etc).

BTW, I see that Rational (now IBM) lists pthreads-win32 amongst it's 
third party components for the following products:

Rational Test Manager, Rational Quality Architect, Rational Robot, 
Rational TestSuite
