>Description:
Environment is a simulated MicroVAX 3900 (SIMH).  Stock NetBSD kernel built by the NetBSD releng.

Running an ATF test plan causes atf-run to dump core.  I haven't looked deeper into under what circumstances it crashes (I don't know specifically if it's because a test case fails, for example).  Upon further inspection, it crashes with standard tests in /usr/tests, as well.

This same test program runs fine on x86(32,64), sparc, and arm(32,64).

 Stack unwinding is broken, see port-vax/44155

 I think this is a g++ general bug on the vax. Does any c++ program work?

 Last I looked only exception unwinding failed.

 Indeed, and unwinding failure leads to abort().

 Yes, and atf uses that I think.
