PR #8409 fixes one part of it but there are more things left.

Instructions for people to test:

  1. Compile FRR without ASAN (this is the default)

  2. Add this patch to your topotest:

    diff --git a/tests/topotests/lib/topotest.py b/tests/topotests/lib/topotest.py

                    daemon_opts, daemon
                )

  3. Before running topotest create the valgrind output directory: mkdir /tmp/valgrind ; chmod 1777 /tmp/valgrind

  4. Run the bfd-topo2 topology test

  5. Read the /tmp/valgrind/* files
