A combination of options can yield the error:
internal compiler error: in remove_unreachable_handlers, at tree-eh.c
To produce the error, g++ is invoked thus:
g++ -c -pipe --trapv --non-call-exceptions --stack-check -O2
Aside from -pipe and -O2, which can be further decomposed, the options are the
minimal set to produce the error in this case.
