This one is really picky about C[XX]FLAGS. Please try with much simpler ones
(definitely remove "-funroll-loops -mmmx -msse -msse2 -mfpmath=sse"). I'd
suggest something really simple, like "-O2 -march=pentium3"

Might Fedora's ocaml gcc4 patch (
http://cvs.fedora.redhat.com/viewcvs/*checkout*/devel/ocaml/ocaml-num-gcc4.patch?root=extras
) fix this?

Yes, it does. This bug is also fixed in Ocaml 3.08.4

[Comment 4 Matthieu Sozeau (RETIRED) 2005-09-21 11:53:24 UTC]

I'll add the patch to the 08.3 ebuild, 08.4 is coming this night. 

[Comment 5 Matthieu Sozeau (RETIRED) 2005-09-21 11:58:56 UTC]

I messed up, the patch is already in 08.3 since 25/07(see #97186), and 08.4 is  
coming soon.
