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

[a dot l dot sveikauskas at gmail dot com]

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.

Hmm, shouldn't the unwinder using pthreads mutex's already?

What is the output of "gcc -v" is the thread model set to single?

I can reproduce with mainline on a bi-processor machine (Sun-Fire-V240) running
Solaris 10 but neither on a bi-processor machine (Sun-Fire-V240) runnning
Solaris 9 nor on a quadri-processor machine (Sun-Fire-V440) running Solaris 8.
