I noticed that a new unit test added by this series is failing for me on
Ubuntu 20.04, which has libgmp.so.10.4.0 :

 $ ./gdb -ex "maint selftest gdb_mpq_write_fixed_point"
 GNU gdb (GDB) 11.0.50.20201116-git
 ...
 Running selftest gdb_mpq_write_fixed_point.
 *** stack smashing detected ***: terminated
 Aborted (core dumped)
 $

I've built a clean gdb from scratch to confirm.

The test passes on Fedora 27, which has libgmp.so.10.3.2:

 $ ./gdb -ex "maint selftest gdb_mpq_write_fixed_point"
 GNU gdb (GDB) 11.0.50.20201116-git
 Running selftest gdb_mpq_write_fixed_point.
 Ran 1 unit tests, 0 failed

Anyone else seeing this?
