Bug in pthread ?

Hello,
Here is the problem:
if I don't "initialiaze" the mutex in the constructor, it works in any case.
but if I "initialize" it, it worked with cygwin1.dll (v1.3.2) and not
anymore with cygwin1.dll (v1.3.3)
when calling the function "fct", the program waits forever on the
"pthread_mutex_lock" instruction (and if I debug it with GDB: &_mutex is
NULL)
so, is it a bug or is it normal ???
class A {
public:
A();
void fct(void);
private:
pthread_mutex_t _mutex;
pthread_mutexattr_t _mutex_attr;
};
A::A() {
pthread_mutexattr_init(&_mutex_attr);
pthread_mutex_init(&_mutex, &_mutex_attr);
pthread_mutex_unlock(&_mutex); /*********** BUG ??? **************/
}
void A::fct(void) {
pthread_mutex_lock(&_mutex); /********** WAITING HERE ... ************/
...
pthread_mutex_unlock(&_mutex);
}
