Ok, the problem is that some files #define NDEBUG, others don't, and if you
link a file compiled with NDEBUG that includes
boost/date_time/posix_time/posix_time.hpp, with one that includes it w/o
defining NDEBUG then bad things happen.

With gcc at -O1 everything is fine, and the result is valgrind clean, however
even with gcc at -O0 it segfaults if one files defines it, and the other one
doesn't.

Now llvm-gcc at -O1 optimized things differently and preserved the bad
behaviour.

Doesn't look like a bug in LLVM, sorry for the noise.
