Hello,
what happens with deal.II 7.1 or the developer version of deal.II?
deal.II 6.3.1 is a bit of outdated.
Best Regards,
Markus

Hello everyone,
I'm using the version 6.3.1 of the Deal.II library for some reason
Step-9 is giving me a memory corruption problem related to the threads
launched by this step.
The code is segfaulting when it launches the first thread in assemble_system().
Did it happen to anyone else? Anyone know what may be happening?
I'm in a 64 bits Debian wheezy distribution, my computer has 4 cores,
the code must be launching 4 threads.
I attach the stacktrace:
