Summary

0001110: sed and grep don't work inside backticks is static-busybox

Description

I've also posted this bug here:
http://bugs.gentoo.org/show_bug.cgi?id=157118 [^]

Short copy-paste:

busybox sh
TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST
# gives abc, as expected

busybox.static sh
TEST="`echo abc | sed -n '/abc/p'`"; echo $TEST
# gives empty line!!!!!!!

This bug hit me when trying to make an initramfs (hence the need for the static
binary); it took me 3 hours to pin it down to the usage of sed INSIDE backticks
(or the $() construct).

This also fails: echo `echo abc | grep abc`
this works: echo `echo abc | awk '/abc/p'`

I tried this bug on 3 different machines and was able to reproduce it on version 1.2.2.1; this bug does not exist on 1.1.0 and 1.2.1

Additional Information

I'm using the default gentoo ebuild; so I don't know very much about all options used at compile time; But I can forward the question to the gentoo-guys, or try to find the answer myself.
