You should, with a current bash devel, just be able to run

make clean
make valgrind

That disables some bash malloc wrapping functions that confuse valgrind
severely. Then just run

valgrind bash
or
valgrind --leak-check=full bash

and see what you get. (Assuming you have valgrind installed, of course, and
depending on what you want to find out).

If you want to try address sanitizer, make sure you have a compiler that
supports it, then run

make clean
make asan

I put the shorthand targets in for convenience. Once you build a bash with
address sanitizer support, you just have to run it and see what it reports.
