hi Dima, I am familiar with reduction modulo Euler totient,
but it could be expensive to compute and in addition my testcase
omits it on purpose :)
btw, in the github issue the link to google groups appears
broken.

cause X has a different type here, so it does not hit the buggy line.

In quite a few places in Sage code on still sees PyInt_AS_LONG - which
is obsolete.
Just recently is caused trouble: https://github.com/sagemath/sage/issues/36080
Some places have ad hoc redefines of it to PyLong_..., e.g. in
src/sage/geometry/triangulation/triangulations.h:
#define PyInt_AS_LONG
