This is a bug to track two related upstream PRs, one for gdb and one for the kernel: - https://sourceware.org/bugzilla/show_bug.cgi?id=31486 "[gdb/tdep, aarch64] Hang when hitting access watchpoint on M1" - https://bugzilla.kernel.org/show_bug.cgi?id=218628 "Aarch64 inexact watchpoint address make SIGTRAP hard to interpret" Sofar I only managed to reproduce the problem on macbook M1, but it might also occur with new server hardware supporting SVE or the MOPS feature.
