Thread: Interval regression test failing with -march=pentium4

I'm compiling postgresql 8.1.3 with these gcc flags: -march=pentium4 -O3

The compilation ends correctly but the interval regression test fails.
This is the diff file:

=====================================================================

*** ./expected/interval.out     Thu Mar 23 15:38:42 2006
--- ./results/interval.out      Thu Mar 23 16:16:06 2006

  -- test long interval input

  -- test long interval input

If i compile the -march=i586 the regression test reports no problems.
Any tips?

Thank you,
