[Message part 1 (text/plain, inline)]
This bug appears in GNU grep version 2.20. It is not present in the older
version I have installed on a home system (2.6.3.)

test case (single line)
abchelloabc

grep does not find the line with grep -e '^hello'  nor with grep -e 'hello$'
however, the line is output with
grep -e '^hello' -e 'hello$'

I downloaded, built and tested the bug on GNU grep 2.21 and it still
appears.

weird.

(this was found by an introductory Linux student. )
