Does PERL assume float is IEEE format?  That would of course be a bad assumption, and if so, it would be their bug to fix.

I remember reports of compiler crashes, and those of course would be compiler bugs to be fixed.  One of them had to do with mishandling FFS, for which I proposed a fix a while ago that recently was picked up by Felix.  What happens at times is that there are compiler issues that only get triggered by the right combination of compile flags (say, -O2) and/or the exactly right magic source code.

GCC/VAX has a maintainer but I'm not sure if he's been able to spend time on it recently.  Others can submit patches, of course; backend fixes are often not that hard to figure out.
