Well, you can never be entierly sure, but it fails in this line[1]
and I don't really see that happening unless malloc returns NULL.<br>
<br>
Do you still have the core file? Could you do a "bt full"+"info
registers"+"disassemble lcnt_thread_data_alloc" on the thread that
fails?<br>

This happens when malloc returns NULL. I'll add a check so
that there is a nicer error message, but there is not much
we can do when there is no memory left.<br>
