Assuming you want to remap 134 to 0 (success):

#!/bin/bash

cmd="$1"
shift 2>/dev/null

$cmd "$@"
[ $? = 134 ] && exit 0 || exit 1

The exit status of the `./array_ex` call (as seen from bash) is 
134. How do I, in Bash, map that exit status to zero, and all 
other exit statuses to non-zero?


Solution construct a Bash script named, say show-segfault:


#!/usr/bin/env python3

import sys
import pty

stat = pty.spawn(sys.argv[1:])
if stat == 256:
exit(42)# remap to 42
else:
exit(stat)


and wrap call to rdmd as


show-segfault rdmd ...

Next try:

dustmite --no-redirect src "dmd -main -unittest -g -debug 
array_ex container_traits searching_ex && { ./array_ex; } > 
grep SIGABRT log"


but that fails too as

Loading src/w3c.html

I can't get ! operator to work either.

If you see output even after redirecting stdout and stderr, the 
program is probably writing to /dev/tty or similar.


I'm not sure what the "proper" way is to run a program without a 
TTY... but what happens if you run the program via ssh, without 
allocating a PTY? I.e. with -T, or with a command and without -t.
