Their expectation simply does not work *at all* because they do something (setting SIGFPE to SIG_IGN) which is completely ignored on at least one major platform (x86 linux) for longer than it has git history.
Their math code seems to work around generating such errors, but I find it rather hard to read (or rather read & understand). Doing what I proposed admittedly has the issue that we would jump out of perl code without much ado. I have no idea whats the proper perly way to do so is. It just seems we should do something... if (in_perl) return; Would be the equivalent of what they want?
