Seems to be working in the cygwin I d/l on july 1.
Strange... but glad that it works.

Thanks for all your help.

Strange indeed, I will try that, but in the meanwhile,

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
with no results. The following program is used to determine if the
exception context is thread-specific or not:

I have build gcc-2.95.3-5 with --disable-shared --enable-threads
(and without --enable-sjlj-exceptions, but this should be the default)
and i get

func() - eh_context = 970EB0
func() - eh_context = 971368
Great! Exception Stacks Differ.
