Details Responder

Subshells always return status 0 in EXIT traps.

$ yash -c 'trap "(false) && echo BUG" EXIT'
BUG
$ yash -c 'trap "(false); echo \$?" EXIT'
0

Workaround: if an explicit 'exit' is given, it works as expected.

$ yash -c 'trap "(false; exit \$?); echo \$?" EXIT'
1

Background info: dash has a similar bug, and the relevant thread there is probably worth following.
