Hi, I just stepped over a difference between bash and busybox. To illustrate I wrote this simple script:
----------
#!/bin/sh
bar () { echo -n $foo; }
foo=1
bar
foo=2 bar
bar
----------
bash, zsh, posh output 121
busybox sh, dash, (m)ksh output 122
checkbashisms doesn't complain.
Which of the three is wrong? Where shall I file bugs?
When bar is not a function but an external script the output is 121 with all
the shells.
Greetings
Timo
