It's true that it isn't completely reliable, but it's usually "good

walking off into the epilogue, for instance, as this code is currently
somewhat prone to.
What version of GCC are you using? Perhaps I can reproduce it with a
different version.

This, though, I probably can't without access to an OpenBSD system...
