Description Mike Jennings 2006-08-17 17:57:41 UTC 
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 ***
Aborted

however exporting my lang to EN_US it works

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

Can anyone test this on a EL4-U4 vs non U4 system?
