4736	MinGW: tss crashes (SIGSEGV) in ~thread_specific_ptr	Jim Bell <jim@…>	Anthony Williams	"tss crashes with a SIGSEGV in the destructor of thread_specific_ptr under mingw, inside boost::detail::set_tss_data().

After main() exits, apparently cleanup_tls_key() gets called some time prior to the thread_specific_ptr clean-up.

Then inside set_tss_data(), get_or_make_current_thread_data() returns 0, and dereferencing it (current_thread_data->tss_data, line 589) causes the crash.

get_or_make_... actually makes one, but get_current_thread_data() won't return it because current_thread_tls_key is reset. So there's a little resource leak here, too. Though I don't think that's important this late in the program's termination sequence, you could check current_thread_tls_key explicitly in get_or_make_... and avoid it.
