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

We still need a self contained testcase to reproduce this issue.
I tried producing one, but it seems that this would take me much more time
than I can currently afford, especially

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

I reconfigured with
CFLAGS=-m32 -O2

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.
