3.1 build failure on x86

[Tom Tromey]

I'm using CVS trunk on x86 Red Hat Linux 6.2.

If I compile libgcj with `-g' I see this failure:

../../../gcc/libjava/jni.cc: In function `void 
   _Jv_JNI_CallAnyVoidMethodV(JNIEnv*, java::lang::Object*, java::lang::Class*,    _Jv_Method*, void*) [with invocation_type style = normal]':
../../../gcc/libjava/jni.cc:903:   instantiated from here
../../../gcc/libjava/jni.cc:819: Internal compiler error in 
   fixup_abnormal_edges, at reload1.c:9514

If I recompile with `-g -O2' then it works.
