[Python-apps-team] Bug#825476: cython: FTBFS with gcc-6 and glibc 2.23: Test failures

[Daniel Schepler]

Source: cython
Version: 0.23.4+git4-g7eed8d8-1
Severity: important

>From my pbuilder build log (on amd64), using a chroot preferring
gcc-defaults and glibc from experimental:

...
Doctest: cppwrap.__test__.voidfunc (line 36) ... ok
test_embed (__main__.EmbedTest) ... ok
