10943	SIGSEGV in compiler_log_formatter::log_start	InonShar@…	Gennadiy Rozental	"= SIGSEGV in output::compiler_log_formatter::log_start() call to ostream::_M_insert<unsigned long>() =

Hi!

I'm trying to compile a code which uses the Boost.Test module, and while playing around with some of the parameters it seems to have broken: I now get a segmentation fault whenever I run the code, at the printout of the first line to the log file. The custom-named log file exists, but is empty, and no error message is emitted.

My setup is done using the following code, after which a BOOST_GLOBAL_FIXTURE is initiallized (succesfully). If I understand the stack trace, the error seems to occur only when starting to traverse the test_unit tree.
