If I change @(.L9,er0) to @.L9, I don't get the error any more. I am currently getting a lot of failures in gcc testsuite, and I am wondering if they all come from the same reason. I haven't figures out how this happens or which patch is causing this. The problem occurs with or without http://sources.redhat.com/ml/gdb-patches/2003-07/msg00053.html Kazu Hirata
