IMO these should be fixed before we unmask: |
| 10 |
|
| 11 |
546742: x11-apps/sessreg-1.1.0 fail to build with gcc5 |
| 12 |
547626: dev-lang/python-3.3 / 3.4 test_faulthandler hangs with GCC 5.1 |
| 13 |
547950: app-shells/zsh-5.0.7-r2 builds but has runtime errors with GCC 5 |
| 14 |
555866: media-libs/phonon-4.8.3-r1[qt5] fails to build with gcc-5 |
| 15 |
