[Bug c++/32344] New: Exception handling crash on multi-threaded Solaris/Sparc

["a dot l dot sveikauskas at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

On multiprocessor Solaris Sparc machines, if multiple threads are concurrently
throwing exceptions, and another thread is calling exit() or returning from
main(), there are messages such as:

   terminate called recursively
   terminate called after throwing an instance of '

And sometimes core is dumped with an abort signal.

I have been able to reproduce this on a number of different gcc versions
(4.2.0, 4.1.2, 2.95.2).  You can find the code I use to reproduce it at:
http://www.csug.rochester.edu/users/ugrads/asveikau/exception_bug.cc  Note that
running it once without incident does not mean the system is unaffected by the
bug; keep running it until it dumps core.

The code runs file on: SunPRO C++ on the affected systems, gcc 4.1.1 on i386
linux, and gcc 3.2.3 on i386 linux.  This is why I concluded that the issue is
specific to either gcc on Solaris or gcc on Sparc.  Since it works fine on
Sun's compiler, I don't think it is Solaris's fault.  I don't have access to
sparc linux or x86 solaris, so I couldn't narrow it down beyond that.
