I don't think that "catch throw" works on any GNU/Linux target right
now. I've got it about half re-implemented for GCC 3.x in a scratch
directory right now but I don't know when I'm going to have time to
test it.
You can get just about the same effect in GCC 3.x by putting a
breakpoint on __cxa_throw. In 2.x I think it was __throw.
