F_pass and FArgs_pass tests segfault

[andrej.krutak@…]

Both tests override the operator new and inside it, they use std::cout.

It appears that in some cases the order of initialization (ostream vs. boost) order may be incorrect and the following exception occurs in ostream:

Program received signal SIGSEGV, Segmentation fault. 0xb7f5a296 in std::ostream::sentry::sentry (this=0xbffffca8, os=...)

After commenting out the std::cout line, both tests pass.

Thanks for the report. Fortunately this is only a test issue.
