When alias expansion is enabled for a script in bash native mode,
prefixing POSIXLY_CORRECT=y to any command will turn alias expansion
globally off. This is a bug because the assignment should only have
effect on that command.
$ bash -c 'shopt -s expand_aliases; shopt|grep expand_a;
POSIXLY_CORRECT=y true; shopt|grep expand_a'
expand_aliases on
expand_aliases off
Expected behaviour: alias expansion should stay on.
I've confirmed this bug on bash 4.2 and later; bash 4.1 and earlier seem
fine.
