Recent changes to gcc have caused cygwin's method of invoking some asm
code in exceptions.cc whiched called a signal handler to be optimized
away. I had worked around this in a kludgey fashion but now I've
rewritten things in a way that should not break if compilation becomes
more aggressive in the future.
What does this mean? It means that signals are handled in a different
way in tonight's snapshot and that no one will notice anything
whatsoever. If I'm lucky.
Either that or you'll be seeing "core dumps" every time a process reacts
to a signal which has a handler associated with it. If I'm unlucky.
Please be on the lookout for these kind of problems. They shouldn't be
hard to notice. If you can provide a simple test case that illustrates
a break I'll be very grateful.
