I am not able to reproduce this on x86_64-unknown-linux-gnu g++ (GCC) 4.1.1 20060525 (Red Hat 4.1.1-1) i686-pc-linux-gnu g++ (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) I have no idea if this is becuase my environment is different from the one run at the automatic regresson tester or if this is compiler problem that has been fixed in dot-releases. -- Lgb
