I had the same problem with RH Enterprise 3.0 U2 on a dual opteron.  The 
problem is in the choice of fixed point arithmetic implementation.  Basically 
configure sets it to FPM_INTEL when it should be FPM_64BIT.

In the configure script you should have from lines 29484 to 29497 ...

  x86_64-*)
    CFLAGS=" -fomit-frame-pointer $m_wm $m_psb -fexpensive-optimizations $f_si 
$f_nsa -ffast-math -funroll-loops -finline-functions $CFLAGS"
    DEBUG_CFLAGS="-O0 -g $DEBUG_CFLAGS"

cat >>confdefs.h <<_ACEOF
#define ARCH_X86_64
_ACEOF


cat >>confdefs.h <<\_ACEOF
#define FPM_INTEL 1
_ACEOF

    ;;


The problem is line 29494 ...

	#define FPM_INTEL 1

it should be ...

	#define FPM_64BIT 1


The only problem you might have with the above is that the line numbers are 
wrong.  My configure script is probably a little different from yours.

If anyone else is interested I'm attaching a patch to configure.ac so autoconf 
will generate the correct configure script.

I found this solution from http://bugs.gentoo.org/show_bug.cgi?id=49569
