I'll try to investigate further what's going wrong there (sorry, I'm being
slow on this)

Indeed. With printouts I tracked down the issue to ring creation in
{{{src/sage/libs/singular/ring.pyx}}}
I guess that I incorrectly assembly the minpoly in ring construction
(omalloc magic or whatever)
Or there is an issue with the {{{AlgExtInfo}}} declaration or in
{{{nInitChar()}}} call.
Could you take a look or even fix it?
See the corresponding Singular example {{{test_Q_Ext_a()}}} in
{{{latest/libpolys/tests/polys_test.h}}}
