Concurrent posix_time streaming crashes

Description
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.
Could this be related to Tickets 3961, 3369 or 4846.
Build command-lines:
MinGW:
g++ -DBOOST_THREAD_USE_LIB DTConcur.cpp
-IC:\Software\Open\lib\boost_1_45_0\ -DWIN32 -D_WINDOWS
-LC:\Software\Open\lib\boost_1_45_0\mgw44\lib -mthreads -g -frtti
-fexceptions -mthreads -Wall -lstdc++ -lmingw32 -o DTConcur
-lboost_thread-mgw44-mt-s-1_45
VC8:
cl DTConcur.cpp /IC:\Software\Open\lib\boost_1_45_0\ /MT /D
BOOST_THREAD_USE_LIB /GR /EHsc /D "WIN32" /D "_WINDOWS" /FeDTConcur.exe
/link /LIBPATH:C:\Software\Open\lib\boost_1_45_0\msvc8\lib

This is most likely caused by MinGW Issue 2843440, stemming from a thread safety problem with msvcrt.dll and iostream imbue.
This is still an issue on Windows XP SP3 (as of March, 2011).
Work-around (empirically): mutex all streaming over the entire life of the stream object, including constructor and destructor.
