I was trying to apply CMEM unit to my small example with pthreads, and
had following : if i set cmem before pthreads unit it crashes on
program initialization before my code executed, if i put cmem after ,
all works good except that, now its crashes in finalization stage,
after my code already executed. But in bigger project which i need to
run it doesnt matter where i put it, it crashes at start anyways.
Who can give advice how to fix it please ? I can show strace logs
where it happens.

Best regards,
