grep

[Eugene]

Hi there!

I installed grep-2.5.1-431.i586.rpm package on SuSE 9.1 platform and found 
some strange behaviour:


bash-2.05b$ echo "_8_5" | egrep -q '^(_([0-9]|2[0-5])){2}$' && echo true || 
echo false 
true

bash-2.05b$ echo "_8_6" | egrep -q '^(_([0-9]|2[0-5])){2}$' && echo true || 
echo false 
false

bash-2.05b$ echo "_8_6" | egrep -q '^(_(2[0-5]|[0-9])){2}$' && echo true || 
echo false
true

bash-2.05b$ egrep --version
egrep (GNU grep) 2.5.1

It seems to me that the 2nd case is wrong.
The same behaviour I found on the RH9


bash-2.05b$ echo "_8_6" | egrep -q '^(_([0-9]|2[0-5])){2}$' && echo true || 
echo false 
false

bash-2.05b$  egrep --version
