[root@devel etc]# 

Version-Release number of selected component (if applicable):
grep-2.5.1-31

How reproducible:
Sometimes

Steps to Reproduce:
1. cd /etc
2. grep -R "ttyS0" *
3.
    

Actual Results:  segfault

Expected Results:  finish my grep

Additional info:

I'm not sure what it is segfaulting on - there is some period of time
after the last grep error before it segfaults.

Comment 1 Tim Waugh 2004-11-30 08:42:44 UTC
Please install grep-debuginfo-2.5.1-31 from:

  ftp://download.fedora.redhat.com/pub/fedora/linux/core/3/i386/debug/

Then run:

  cd /etc
  gdb --args grep -R "ttyS0" *
  (gdb) run

When it crashes, type: bt (and press enter).  What does it say?

Comment 2 Tim Waugh 2004-11-30 08:45:36 UTC
Actually, before you do that does running 'dmesg' after the grep command show a
kernel oops? (If not continue as in comment #1)

Comment 3 Michael A. Peters 2004-11-30 09:12:20 UTC

Comment 4 Tim Waugh 2004-11-30 09:22:59 UTC
And dmesg?

Comment 5 Michael A. Peters 2004-11-30 09:38:19 UTC
Created attachment 107611 [details]
dmesg > dmesg.txt

Comment 6 Michael A. Peters 2004-11-30 09:40:27 UTC

Not sure what is causing those, been there like crazy since the FC3Test2 (never
ran Test1) - but they are probably unrelated

Comment 7 Tim Waugh 2004-11-30 10:03:38 UTC
This is a kernel oops caused by the nvidia module:

[<13172525>] nv_alloc_file_private+0x11f/0x13a [nvidia]

Comment 9 Michael A. Peters 2004-11-30 10:05:13 UTC
Yeah - I just booted w/o nvidia and grep works.
