Wolfgang,

I don't know where the connection is. You're of course right, these are two different things. We got confused because the mutex underlying TaskGroup<>::join_all is handled by boost (or by the c++0x library directly), which popped up in gdb. > So in essence I'm afraid I'm not of much help.

We'll come back if we discover anything new... Best, Katharina and Martin _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
