lock in qnx rtp.

Hello,
    I'm porting posgresql for QNX RTP. Compiling is ok, but
"/usr/local/pqsql/bin/initdb -D data" command say:

FATAL: s_lock(0x081e6029) at spin.c:162, stuck spinlock. Aborting.

FATAL: s_lock(0x081e6029) at spin.c:162, stuck spinlock. Aborting.
sed: couldn't write 86 items to {standard output}: Broken pipe
Abort (core dumped)

initdb failed.
Data directory dat will not be removed at user's reques



I review sem_'s  family functions and use de QNX sem function, except
S_LOCK_FREE:

It is in  src/include/storing/s_lock.h
    #define S_LOCK_FREE(lock)   s_lock_free_x86(lock)
    #define TAS(lock)           (sem_trywait((lock)) < 0)
    #define S_UNLOCK(lock)      sem_post((lock))
    #define S_INIT_LOCK(lock)   sem_init((lock), 1, 1)

It is in  src/backend/port/x86/sem.c and make for my
    int
    s_lock_free_x86(sem_t *lock) {
      int value;
      sem_getvalue(lock, &value);
      return value;
    };

The testing program "s_lock_test" (is inside in s_lock.c) working properly.

Any idea. Sorry for my english.

Thanks,
