Comment 2 ernsteiswuerfel archtester 2019-12-03 00:15:46 UTC 
Out of curiosity I run the full testsuite (built v1.8.1 from upstream git) and reported the bug upstream.

Comment 3 Rolf Eike Beer archtester 2021-06-12 18:30:06 UTC 
The alignment test also shows that this doesn't handle alignment properly as seen on sparc:

    media-libs/libvpx: add 1.11.0
    
    Notably now forcing specific targets only where we
    know libvpx works well and otherwise using
    the generic implementation due to
    runtime breakage (and extensive test failures).

    media-libs/libvpx: drop to ~sparc
    
    Too many test failures. Unclear if it truly works at runtime.

Comment 9 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-05-11 00:50:41 UTC 
ernsteiswuerfel, does it work OK at runtime or should we try drop it somehow for stable ppc?

In extremely dire state on BE mips as well, see test log.  No segfaults, but 192 failures out of 954 total.
