Replying to [comment:25 vbraun]:
> Ok this should fix it now for good. The first patch introduces
refcounting for Singular ring pointers and uses it in `GroebnerStrategy`,
and the second updates `MPolynomialRing_libsingular` and
`MPolynomial_libsingular`. Please give it a try with Python-2.7...
OK, I applied both the singular_rings and singular_polynomials patches to
the 4.7.1.alpha2 that I have and built Sage as in comment:18 . As noted
above this is not a pristine 4.7.1.alpha2, but has other python-2.7
related patches included; tickets #11377, #11244, #9958,
#11376 and #10764. There are no segfaults. The testsuite looks like the
results when the bug11339a.patch was applied. And I don't get the Killed
doctest mentioned by François. Now with just the singular_rings patch I
also get no segfaults or crashes. Should I get a crash? I can't see that
any of the applied patches could affect things. I will build from scratch,
just to make sure.
