Description Michal Marek 2005-04-21 19:03:59 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Fedora/1.7.6-1.3.2

Description of problem:
After building a custom Python RPM, the daily prelink run segfaulted when prelinking /usr/lib/debug/usr/bin/python.debug. It's nothing critical, since the python.debug file is probably broken anyway, but prelink should print a warning message and continue instead. I wrote a quick patch which just silently ignores it, will attach that.

Version-Release number of selected component (if applicable):
prelink-0.3.3, prelink-0.3.4 from devel too

How reproducible:
Always

Steps to Reproduce:
1. Create a corrupted ELF file (will attach one)
2. run 'prelink /path/to/file' or 'prelink -a'

  

Actual Results:  Segmentation fault (core dumped)


Expected Results:  "File %s is corrupted, not prelinking" or something like that.

Additional info:

Only special configuration is that debug file I'll attach, everything else is a normal FC3 install.

Must have pressed that button twice...
