Dear all,
The following crash related to `execute_builtin` was found by a modified version of the kAFL fuzzer (https://github.com/RUB-SysSec/kAFL).
I have attached the binary and all related crashing inputs grouped by the last 5 call-stack functions and input, each with a back-trace and context (containing color).
To reproduce the crash issue, execute the binary of bash with the crashing input as script (./bash < <crashing_input>).

We can verify all issues for GNU bash, version 4.4.23(2) (x86_64-unknown-linux-gnu) (git commit 64447609994bfddeef1061948022c074093e9a9f).
