Nice: the arm64 build failed exactly as predicted (cf this travis log), i.e. we can reproduce the reports by @jamesjer and Bill. I'll now add the fix to this PR to see if it really helps. |
Besides just adding three jobs to the Travis build matrix, we have to deal with some issues with the VMs for the three new platforms: - Always call the right pip matching the `python` binary; and prepare for `python` being Python 3. For details, see <https://travis-ci.community/t/8165> - Work around the fact that the pip cache dir is owned by root. For details, see <https://travis-ci.community/t/7822/6> - Use travis_terminate liberally in .travis.yml to workaround another issue with the three new platforms; as a side benefit, we also get Travis to reliably and early on abort CI builds with failures. For details, see <https://travis-ci.community/t/7659/>. - Adjust a test for OPERS_CACHE_INFO to pass on the three new platforms.
Inlining this function can break the garbage collector. This was the case on Linux aarch64. Thanks to Jerry James (Fedora) and Bill Allombert (Debian) for help tracking this down. Fixes gap-system#3919

Besides just adding three jobs to the Travis build matrix, we have to
deal with some issues with the VMs for the three new platforms:
Switch to using Python 3 instead of Python 2 to workaround an issue wherepythonispython2.7butpipispip3.6.Always call the right pip matching the

Adjust a test for
OPERS_CACHE_INFOto pass on the three new platforms.This is a backport of PR #3744. I am hoping that we see the crash from issue #3919 so that we can then test PR #3965.
