numrun012 test fails on i686 works on x86_64
I have built ghc on both x86_64 and i686 for archlinux. make test has no unexpected results on x86_64. On i686, make test has only the following unexpected failure:
=====> numrun012(normal) 831 of 3160 [0, 0, 0]
cd ./numeric/should_run && '/build/src/ghc-7.4.1/inplace/bin/ghc-stage2' -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-conf -rtsopts -fno-ghci-history -o numrun012 numrun012.hs >numrun012.comp.stderr 2>&1
cd ./numeric/should_run && ./numrun012 </dev/null >numrun012.run.stdout 2>numrun012.run.stderr
Actual stdout output differs from expected:
--- ./numeric/should_run/numrun012.stdout 2012-02-01 18:11:16.000000000 +0000
+++ ./numeric/should_run/numrun012.run.stdout 2012-02-07 23:06:57.413192194 +0000

*** unexpected failure for numrun012(normal)I think I got the failure down to one line:
The following returns 31.000000000000004 on x86_64 and 31.0 on i686:
logBase 2 (fromIntegral 2^31) :: DoublePlease let me know if you need anything else from me.
