Description Karel Volný 2007-10-29 08:25:34 UTC
Description of problem:
When trying to run foremost with verbose option, it crashes on opening the 
audit file.

Version-Release number of selected component (if applicable):
foremost-1.5-1.fc7

How reproducible:
always

Steps to Reproduce:
1. in my case, run 'foremost -v -i /dev/sdb7'
  
Actual results:
Segmentation fault

Expected results:
normal operation :-)

Additional info:
This did not happen last time I used foremost (1.5) on my Gentoo box, so I 
report against Fedora rather than upstream.

Comment 1 Toshio Ernie Kuratomi 2007-12-04 19:49:58 UTC
It looks like the problem is that var args handling in the audit_msg() function
is wrong.  This is only showing up on x86_64 which may be why you're not seeing
it on Gentoo.  Patch applied and building now.

Comment 2 Toshio Ernie Kuratomi 2007-12-04 23:35:09 UTC
* Patches accepted upstream.
* Bodhi should be pushing the patched version to the testing repository soon.
