Created attachment 318728 [details] emerge fail log =dev-lang/python-3.2.3-r1 fails tests with clang-3.1-r4, latest stable in slot (3.2.3) fails also, I didn't test other versions in the slot.
If someone can try this with libffi-3.0.12, that would be awesome.
Both python-3.2.5-r3 and python-3.3.3 still fail the test phase. clang-3.4.2, libffi 3.0.13-r1.
Retested both python-3.2.5 and python-3.3.3. python-3.2.5 still fails on the alarm clock test. python-3.3.3 instead tests fine. Some test issues were due to /etc/localtime not being set. Symlinking to my current timezone made the tests pass just fine. libffi 3.0.13-r1.
python-2.7.10-r1.ebuild python-2.7.11-r2.ebuild python-3.3.5-r3.ebuild python-3.3.5-r8.ebuild python-3.4.3-r1.ebuild python-3.4.3-r7.ebuild python-3.5.0-r2.ebuild python-3.5.1-r2.ebuild all build with clang 3.5.0 (current stable) and FEATURES=test enabled for me.
I can also confirm with 3.7. Thanks for testing.
