That doesn't help me to reproduce the issue. Please provide output of
appending
-v to the compiler command-line (this must be reproducable on x86_64 with
appropriate flags).

Ok, I reproduced a failure (but none of the kind reported here) and have a fix
for that issue. Maybe it fixes this bug too, which I still can't reproduce.

------- Comment #17 from dominiq at lps dot ens dot fr 2010-09-07 09:12 -------
Also fixed on x86_64-apple-darwin10.4, trunk configured with the default value
for --enable-checking, see
http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg00616.html
The failures on ppc reported in comment #3 have also been fixed, see
http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg00613.html .
Closing as fixed.
