Comment 2 Red Hat Bugzilla 2002-10-15 15:15:09 EDT
I hit this trying to build a PPC cross-binutils (binutils/gas/config/tc-ppc.c).
It seems to only occur with -O (or -O2 in binutils case), so removing -O is a
temporary workaround.
Comment 3 Red Hat Bugzilla 2002-11-27 12:18:50 EST
Should be fixed in gcc-3.2.1-1 in rawhide.
