Re: weird interaction between builtin cat and trap

[Peng Yu]

This code is the even simpler to reproduce the error.

$ cat ./main.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:

enable -f "$BASH_LOADABLES_PATH"/cat cat
trap 'echo EXIT' EXIT
seq 1000000 | builtin cat | {
        :
} {fd}<&0
$  ./main.sh
cat: write error: Broken pipe
EXIT
