This has been submitted to GCC GNATS as PR/7168.

Using the G++ exception system from multiple threads corrupts the gcc's 
internal exception stack, due to not including the thread-specific 
exception context in the compile.
GCC Version: 2.95.3-5 from default Cygwin install.

I tried to re-compile gcc with --enable-threads=posix and with 
--enable-sjlj-exceptions
with no results.  The following program is used to determine if the 
exception context is thread-specific or not:

This prevents any sort of complex exception-sensitive multithreaded C++ 
programs to run in Cygwin/GCC environment.

Thanks for all your help,
Lenny
