This message is listed in the GCC-SIG11-FAQ as one of the messages
you may get when memory is bad.  The latest copy of that FAQ is found at
http://www.bitwizard.nl/sig11.

That same FAQ claims that memory testers don't always find memory
problems, so you may not be able to rely on that test. Sorry...
