Bug Report grep -E Debian Squeeze

[Jean-Marc Messina]

Hi

I hope i report this bug from the good way, if not, please accept my 
aplogies and ignore that mail as it's my first bug report.

OS version : Debian Squeeze (6.0 , 6.2 , 6.7)

Grep version : GNU grep 2.6.3

Bug description :

We have been facing a weird behaviour of "grep -E" on Debian Squeeze 
versions which seems not to happen in lenny or wheezy versions.

Exemple :

echo "tanZANIE" | grep -E '^[a-z]{2,20}$'
No output (normal behaviour)

echo "tanzANIE" | grep -E '^[a-z]{2,20}$'
output : "tanzANIE"

another exemple :

echo "aB" | grep -E '^[a-z]{2,20}$'
output : "aB"

There seem to be a little problem with case sensitiveness or something.

It doesn't happen when using the -P option instead of -E, in this case 
it will work normally.

Hoping it helps.

Best regards,
