Let's apply the patch. We are clearly tickling a bug or near-bug in
gcc, and it may have worse consequences than this on other platforms
or other gcc versions.
At the same time, if anyone wants to trim the existing code down to a
small test case, I'm sure the gcc boys would appreciate a bug report.
