to valgrind. Just add -fsanitize=address to the CFLAGS.
If you can't reproduce the bug with asan I'd bet on a valgrind bug.

I was unable to get this working in gdb, but I added some printf:
pathname 11728

ease drop me a note when you publish it as an "official" patch level
for bash.
Btw, address sanitizer is just a compile feature of gcc and clang
activated by a cflag, you usually don't need anything special to have
it. Makes sense to test from time to time with it.

; char there seems no easy portable way to do
so. Using escaping with \~ works in 4.3, but not in 4.2.
I wanted to ask if this is an expected feature/behaviour change in 4.3
or some kind of bug?
