Description Máirín Duffy 2007-03-26 16:53:55 UTC
Description of problem:

[duffy@host java]$ find . -type f -exec grep -Hi 'bar-undertabs' {} \;
*** glibc detected *** free(): invalid next size (fast): 0x088dff88 ***
find: grep terminated by signal 6

Version-Release number of selected component (if applicable):


How reproducible:

Happens consistently when I run that find command in that directory.

Comment 1 Vitezslav Crhonek 2007-03-27 15:46:51 UTC
thanks for reporting. I can't reproduce it, can you send me for a start path to
java directory? What if you omit find and only grep that directory, e.g. grep
-Hi 'bar-undertabs' * (maybe the problem is in grep, not in findutils).

Comment 3 Vitezslav Crhonek 2007-03-27 16:26:15 UTC
Same problem with:

[root@fjs-0-16 java]# grep -R -Hi 'bar-undertabs' *
*** glibc detected *** free(): invalid next size (fast): 0x09d9d8f8 ***

So I think this is not bug in findutils but in grep -> changing component to grep.

[root@fjs-0-16 java]# rpm -q grep

Comment 4 Stepan Kasal 2007-11-06 16:12:07 UTC
Hi Máirín,are you still able to reproduce the problem on a host?
(If not then there is probably no way to indentify the bug now; I apologize for
the huge delay.)

Comment 5 Máirín Duffy 2007-11-06 16:15:10 UTC
sorry the machine that was reproducing this was blown away a long time ago,
hopefully it's not a problem anymore!

Comment 6 Stepan Kasal 2007-11-06 16:18:41 UTC
So I cannot do anything but close this bug with CANTFIX.

Comment 7 Máirín Duffy 2007-11-19 22:25:45 UTC
Hi Stepan,

I was able to reproduce this again!

is reproduced on!

Comment 8 Máirín Duffy 2007-11-19 22:26:36 UTC
