Valgrind is easily fooled by the bash malloc wrapper functions. There's a
pretty complete explanation here:

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

If you want to run valgrind on bash without false positives, there is a
`valgrind' target in the makefile.

make clean
make valgrind

If the error still occurs with that build, then we'll investigate.
