Yeah, that was a pretty evil bug. It has been lurking there for probably 
18+ years now. It's evil because only a very, very rare set of 
circumstances will trip it, and even then it may not be executed or noticed.

I instrumented the C++ compiler for it, and ran it through its test 
suite. Turns out, it did trip it, but only on a piece of code that was 
tested for compile only. Sigh.

I was glad to get it fixed.
