Comment 1 H.J. Lu 2007-04-28 17:21:45 UTC 
It works with revision 123966:

http://gcc.gnu.org/ml/gcc-testresults/2007-04/msg00980.html

fails with revision 124014:

Comment 2 H.J. Lu 2007-04-28 19:31:36 UTC 
I have verified that this patch

http://gcc.gnu.org/ml/gcc-patches/2007-04/msg01333.html

causes this regression on Linux/x86-64. Richard, can you take a look? Thanks.
