I was able to duplicate this issue on Ubuntu 18.05 x86_64 fully patched.

I've got an easy way to duplicate it, if you want to give it a whirl.
You can really give Asan a thorough testing...

git clone https://github.com/noloader/Build-Scripts
cd Build-Scripts

# One-time setup
./setup-cacerts
./setup-wget

# Build Bash and dependencies with Asan
INSTX_JOBS=5 INSTX_ASAN=1 INSTX_PREFIX=$HOME/ok2delete-asan
<let it build everything under Asan>

# Moment of truth...
$HOME/ok2delete-asan/bin/bash
<crash here>
