Type: Bug

VS Code version: Code - Insiders 1.71.0-insider (eebdf81, 2022-08-12T05:17:00.323Z)
OS version: Windows_NT x64 10.0.19044
Modes:
Sandboxed: Yes
Remote OS version: Linux x64 4.15.0-169-generic

When the original PROMPT_COMMAND is an array:

1. exit code of last executed command is not restored before executing the commands stored inside the original PROMPT_COMMAND array
2. __vsc_status is assigned the exit code of the penultimate command stored inside the original PROMPT_COMMAND array

Those 2 bugs are located in this section of file vs/workbench/contrib/terminal/browser/media/shellIntegration-bash.sh :

__vsc_prompt_cmd_original() {
	__vsc_status="$?"
	# Evaluate the original PROMPT_COMMAND similarly to how bash would normally
	# See https://unix.stackexchange.com/a/672843 for technique
	if [[ ${#__vsc_original_prompt_command[@]} -gt 1 ]]; then
		for cmd in "${__vsc_original_prompt_command[@]}"; do
			__vsc_status="$?"
			eval "${cmd:-}"
		done
	else
		__vsc_restore_exit_code "${__vsc_status}"
		eval "${__vsc_original_prompt_command:-}"
	fi
	__vsc_precmd
}
