Description Agostino Sarubbo gentoo-dev 2020-04-23 14:09:38 UTC
This is an auto-filled bug because media-gfx/fontforge fails tests.
The issue was originally discovered on ppc64, but it may be reproducible on other arches as well.
If you think that a different summary clarifies the issue better, feel free to change it.
Attached build log and emerge --info.

I have reported the issue upstream.

Regarding stabilization, I leave that to the arch team to decide, but keep in mind that this is blocking a security bug.

It seems that only 4 out of 101 tests are failing. Do the tests fail on ppc64 with the previous version of fontforge?

build.log power9 fontforge-20190801

Ok on a ppc64 [BE] VPS running tests for media-gfx/fontforge-20190801 I get two failed tests:

 75: Ligatures and Fractions Table Lookups (with FontForge) FAILED (                                             
 76: Ligatures and Fractions Table Lookups (with Python) FAILED (       

So it looks like we have a regression here.

I've tested 20200314 on little-endian:

100% tests passed, 0 tests failed out of 101 on little-endian ppc64.

I'd say go ahead with stabilization if it's security related. only 2 failing tests on big endian is not good, but not the end of the world.

with patch from

tests now pass 100% on ppc64be
