Description Mike Jennings 2006-08-17 13:57:41 EDT
Description of problem:
grepping for a certain term in case insensitivity mode causes a glibc error

How reproducible:

[mike@michaeljennings ~]$ grep -i "insert into" 1-walkway.jpg 
*** glibc detected *** free(): invalid next size (fast): 0x08df7898 ***

however exporting my lang to EN_US it works

[mike@michaeljennings ~]$ export LANG="en_US"
[mike@michaeljennings ~]$ grep -i "insert into" 1-walkway.jpg
