How to get software recording to work?

(gdb) record full
(gdb) continue
Continuing.
Process record does not support instruction 0xfae64 at address 
0x7ffff7df0f48.
Process record: failed to record execution log.

Program stopped.
0x00007ffff7df0f48 in _dl_runtime_resolve_xsave () from 
/lib64/ld-linux-x86-64.so.2

This is produced in an older environment with GDB 9.2; using a different 
environment with GDB 11.1:

Process record does not support instruction 0xc5 at address 0x7ffff6c79024.
Process record: failed to record execution log.

Program stopped.
0x00007ffff6c79024 in __memset_avx2_unaligned_erms () from 
/usr/lib64/libc.so.6


Can this recording be done reliably? Which places would need to be fixed 
/ adjusted to get this working?

Thanks for any pointers,
Simon
