[Openmcl-devel] compiler bug on AMD64 (problem in error printing?)

[Gary Byers]

Thanks for all of these reports.

That was also broken on the PPC, and had been since at least 1.0.
It's fixed in CVS; I don't think that the fix broke anything else
and can't see any other instances of the same bug, but it's
scary enough that I'd want to keep looking.
