Filed as 17050, with -save-temps source file.

This problem is unique to either 64-bit or Opteron code generation, 
given that my Pentium 4 does not show the same regression. On the other 
hand, Intel produces code that is 6X faster on Pentium 4, suggesting 
that GCC's code generation may be weak there as well.
