3848	Boost.Exception and transporting exceptions between threads	Nikki Chumakov <nikkikom@…>	Emil Dotchevski	"The attached example program exc.cc crashes from time to time.
I suspect that the problem is that detail::error_info_container_impl is not thread safe.

Here is gdb stack trace:
Core was generated by `./exc'.
Program terminated with signal 11, Segmentation fault.
