If this is an aarch64 userspace issue, maybe related to
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107678 ?

That bug causes segfaults of user space programs if for some reason the
unwind code is invoked. It happens only if libgcc_s.so is compiled with
gcc 13, and the pauth CPU feature is enabled in qemu.
