Subject: [Boost-build] Are the boost libraries compatible with _GLIBCXX_DEBUG?

I'm trying to understand a failure in one of my regression tests. The
regression test passes if I use the normal std::vector etc, but fails
(some output numbers printed are slightly different) if I activate
these gcc flags:
>From boost 1.45, I'm using mpi, python, and serialization. I'm using
gcc 4.5.2 on linux, which isn't on the list:
I suspect boost mpi because I was getting a really bug where unrelated
memory was changing during a broadcast statement when boost was
compiled with _GLIBCXX_DEBUG, but my code was compiled without it.
This specific problem goes away if I use _GLIBCXX_DEBUG consistently
between my code and boost. If I turn off _GLIBCXX_DEBUG in both, then
my code passes my regression test, but if I activate _GLIBCXX_DEBUG in
both my code and boost, then my regression fails.
This makes me think that serializing the _GLIBCXX_DEBUG classes is
somehow different... but I don't want to dig into debugging this
people seem to confirm that this could be a problem.
Thanks for any insights!
