[Boost-users] [date_time] Concurrent posix_time streaming crashes under MinGW-32

The attached program crashes under MinGW-32 (gcc-4.4), but works under VC8.

It does concurrent streaming of posix_time::ptime values to a
std::ostringstream.

Mutexing the ostringstream from construction to destruction keeps it
from crashing, but that shouldn't have to be done for independent
streams. Mutexing just the ptime insertions makes it run longer, but it
still crashes.

I'm posting it here instead of taking it straight to Trac to see if
anyone has input. Could it be related to
<https://svn.boost.org/trac/boost/ticket/3961> or
<https://svn.boost.org/trac/boost/ticket/3369>?
