5257,Concurrent posix_time streaming crashes,Jim Bell <jim@…>,az_sw_dude,"The attached program crashes under MinGW-32 gcc-4.4, (but works under VC8).

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

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. And removing concurrency (i.e., running just one thread) allows it to run.
