Hi Bernard,
Many thanks for looking at this, but I'm afraid I still can't see any
obvious solution.

The failing instruction is
500 if (p[3]==1.0) {
I assume the issue is with p[3] rather than 1.0,
but the gbd dump shows p[3] holding a valid value!
(gdb) print p[3]
$8 = 1
If anyone with access to hardware was minded to have a further look,
it might be interesting to see if the program works without
optimisation,
or maybe with just -O1 (set in Makefile.am)
Kind Regards,
Peter
Hello Peter,
Thanks for the suggestion. I have access to the ppc64el hardware, and
I will look into this.
Best Regards,

Hello Peter,
As you suggested, I tried setting the optimization level to -O1 in
Makefile.am, and the program ran without any segmentation faults.
Below are the result :
