bug#18398: Probably found a bug in grep

[Bergen, Andreas]

Hi all,

I've probably found a bug in "grep".
Here's a way how to reproduce it:

s53mgt:/test2 # cat testfile
A
Ä
s53mgt:/test2 # grep -F -eÄ -eA testfile
A
Ä
s53mgt:/test2 # grep -i -eÄ -eA testfile
A
Ä
s53mgt:/test2 # grep -iF -eÄ -eA testfile
A

As you can see the last one does not give A and Ä but only A.

When I do the same with another testfile without an "Ä" (A-Umlaut) in it, it 
works like expected:
s53mgt:/test2 # cat testfile2
A
B
s53mgt:/test2 # grep -F -eB -eA testfile2
A
B
s53mgt:/test2 # grep -i -eB -eA testfile2
A
B
s53mgt:/test2 # grep -iF -eB -eA testfile2
A
B

s53mgt:/test2 # file testfile testfile2
testfile:  UTF-8 Unicode text
testfile2: ASCII text

Here's some information on my version of "grep".

s53mgt:/test2 # rpm -qif /bin/grep

Can you confirm this?

What can I do about it?
