The problem appears to have gone; I cannot reproduce it any more with current
mainline.

I tried producing one, but it seems that this would take me much more time
than I can currently afford, especially since I'm not familiar with GMP.
Sorry...

We still need a self contained testcase to reproduce this issue.

The failure appears to be connected to "-march=pentium4".
The lowest optimisation setting where I could reproduce it is

CFLAGS="-O1 -march=pentium4" ./configure

The test pass with "-O0 -march=pentium4".

I reconfigured with

CFLAGS="-m32 -O2 -fomit-frame-pointer -mtune=pentium4 -march=pentium4
-fno-tree-vrp -fwrapv -fno-strict-aliasing" ./configure

but got the same result as before...

Can you try disabling VRP and enable -fwrapv and -fno-strict-aliasing?  (I also
see failures in other scientific codes with mainline)
