Comment (by SimonKing):
Looking into the upstream sources and trying to find what the gdb
backtrace is telling, I see in line 667 of `pInline2.h`:
{{{
PINLINE2 poly pp_Mult_qq(poly p, poly q, const ring r)
{
poly last;
if (p == NULL || q == NULL) return NULL;
if (pNext(p) == NULL)
{
#ifdef HAVE_PLURAL
if (rIsPluralRing(r))
return nc_mm_Mult_pp(p, q, r);
#endif
return r->p_Procs->pp_Mult_mm(q, p, r, last);
}
}}}
and line 667 is `return nc_mm_Mult_pp(p, q, r)`. That function is defined
in `gring.h` (why in a ''header'' file, by the way?). I find no indication
of "free" being used there, except that it calls
`r->GetNC()->p_Procs.mm_Mult_pp(...)`, and I have no idea where that
method is being defined.
So, I'll ask upstream.
