Sorry, I thought I put that in the original e-mail but did not.  It
applies to gcc 4.2.1 and up I've tested gcc 4.2.1 and gcc 4.3.2).
I've seen some chatter while debugging this that suggested that
gcc-3.4.5 and up were also impacted but I have not independently
verified this.

The gcc bug reports suggests it's been in there for quite some time,
but it doesn't report when it first cropped it's head up either.
