I was the one who originally tracked this down.  Virtually always, when people suspect a problem with gcc or libc, the problem is really in their own code.  This was one of the very rare exceptions, and the gcc folks fixed the optimizer issue.  I'm not sure I see any benefit in looking at or changing the GPG code in an effort to not trigger a bug in a quite old - and long since replaced - version of gcc.
