It turns out this was a short-term Red Hat kernel bug. This bug never exis= ted in upstream Linux kernels, and the bug has been fixed for a while in RH kernels. The virtual machine Alexandra just happened to test on originally still had the broken host OS version. Upgrading to 4.18.0-429.el8 or later kernel resolves this issue. I'm leaving this bug open for now while Luis considers this patch: https://sourceware.org/pipermail/gdb-patches/2023-April/198973.html --=20 You are receiving this mail because: You are on the CC list for the bug.=
