Sounds like libsigsegv knows what it's doing and is only doing what it
should and correctly leaving to Cygwin things best left to Cygwin. (Plus a
quick browse of the source made reinforced that impression; it doesn't replace
but carefully chains in front of the cygwin exception handler and passes
through any exceptions it doesn't eat.)
