I get the following errors with bash 3.2.39 under Debian/unstable:

bash -c 'alias a="echo OK >&2"
 a
 > /dev/null a'
bash: line 1: a: command not found
bash: line 2: a: command not found

$ bash --posix
bash-3.2$ alias a="echo OK >&2"
bash-3.2$ a
OK
bash-3.2$ > /dev/null a
bash: a: command not found
bash-3.2$ 

ksh93 doesn't yield such errors. And concerning the last one, bash is
the only shell I've found that yields such an error.
