No extra compiler flags. BTW I forgot to specify my CPU:
cpu family : 6
model : 26
model name : Intel(R) Xeon(R) CPU L5506 @ 2.13GHz
stepping : 5
microcode : 0x1d
What can I do to track this down? My next step would be upgrading to MPC 1.4.0
(is this library even relevant here?), but I could alternatively upgrade GCC
if you think that makes more sense.
