bug with grep 2.3 - 2.4.2 on Intel Redhat

[Paul Holcomb]

 I have found a bug with grep that manifests itself *at least* with
 version 2.3 and 2.4.2 of grep included with Redhat Intel Linux
 systems. (6.1, 6.2, 7.0, 7.0.90)

 If you have a regular expression ending in 'c*' it matches the letter
 'g' instead of the letter 'c' and vice versa.

 How to replicate:

$> touch soggy
$> ls -l |grep 'soc\*'

-> file matches


$> touch local
$> ls -l |grep 'log\*'

-> file matches



 One gets the same behavior with other variations of escaping or not
 escaping the '*' wildcard character.

 Let me know if you require more detail.  I am going to try to
 replicate this bug on a few other operating systems.
