As expected - when the function is called header is initialized and therefore correct. > My first impression is - the pointer gets corrupted. I'm trying to figure > out the reason.

Sooner of all this is not due to corrupted ptr. If you invoke invalid ptr, you will almost for sure get segfault. I suppose that something goes wrong with file locking on AIX. To continue first of all send me please your src/include/gen/autoconfig.h to let me see which type pf locks is used on AIX. > > I see 2 other threads running, do you know if these threads may affect the > pointer to LockManager::initialize? > They should not. ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
