[GAP Forum] Strange GAP, II

[Anvita]

Dear Forum,

If a pcgs has an element "g" of infinite relative order,
the negative exponents of "g" seem to hang the function
"ExponentsOfPcElement". For example, the program

-------------------------------------------
F:=FreeGroup(1);
g:=F.1;
p := PcgsByPcSequence( FamilyObj(g), [g] );
ExponentsOfPcElement(p,g^-1);
-------------------------------------------

instead of returning -1 runs forever.
It this the expected behavior?
