I managed to capture a core dump.
this was also reported in http://lists.busybox.net/pipermail/busybox/2023-January/090113.html it's caused by having a cpu with AVX512 (the github runners do) but not sha_ni, and the code that checks it is broken and misdetects sha_ni support when avx512 exists. the github runners don't have sha_ni, so it breaks exactly there. quite the rare combo :) i feel this was reported before, but apparently not outside an irc channel.. _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
