# Some basic testing of 'set debug breakpoint on'.  At one point a bug
# meant that some breakpoints would immediately trigger a segfault if
# GDB tried to run with breakpoint debugging turned on.
#
# Test is compiled as C++ only so 'catch catch/throw/rethrow' have a
# something to do.  The original bug would trigger for any 'catch'
# style breakpoint, so C++ isn't really a hard requirement.
