Description
See this sage-devel thread. In short:
sage: t=((1/10)*I/pi)^(3/2) sage: t (1/10*I/pi)^(3/2) sage: t^2
This doesn't return(!), and seems hard to interrupt.

How did you got them ? I wasn't aware of the availability of this steb-by-step tracing...

no, it's not steb-by-step tracing, I just inserted lines in
- symbolic/expression.pyx
- rings/number_field/number_field_element.pyx
- arith/power.pyx
and just reinstalled sage (I use Gentoo Linux)

This will be fixed by the patch to pynac in #30446. When that ticket is closed, we can add this as another doctest.
