Hi Thierry,

This seems to come from the PPL library rather than from a gprolog bug. At least, gprolog has no problem with:

| ?- V is (0.748233316 / 0.262237289) ** 4.

V = 66.278150522301502

When using the GNU Prolog bindings to the PPL library, the following goal leads 
to a segmentation violation, both in the ppl_gprolog top-level and in a 
compiled program.

ppl_initialize, V is (0.748233316 / 0.262237289) ** 4.

This bug disappears when PPL is configured with the --disable-fpmath option.

I have just reported this bug to the PPL library bug tracker too.
