I spent far too long looking for the message that explains this, but here
it is from the archives:

https://lists.gnu.org/archive/html/bug-bash/2017-04/msg00053.html

Bash-5.2 has a `make valgrind' target that will build bash without the
malloc wrappers that so confuse valgrind.

If you want to do that yourself, you have to build bash from scratch with
the DISABLE_MALLOC_WRAPPERS cpp define.
