You need either really old (rwx mmap, which security disables) or really new (static trampolines, which are r-x/rw- mmap'ed) libffi to support that. Hopefully that means your reproducers should not reproduce with the new libffi. > Moreover, rebuild with current Ruby specfiles won't tell you much as > we commented out the tests [2] to have less flaky builds.

Well, if you comment out the tests, I have no way of knowing I broke anything, so have to rely on posting Change Requests and letting you let me know ;-) Not saying you did anything wrong; if you have tests that pass or fail depending on system configurations outside your control, it's difficult to reliably test what you want to test. I'm just saying that when you disable tests, automated processes have no insight into those failures. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
