Description:   Opened: 2007-07-11 15:20 0000 
in /usr/sbin/chkrootkit (version 0.47) in line 181, a blank is missing in the
line "chkutmp()" (should be: "chkutmp ()"). when the interpreter reaches that
line, a segmentation fault occurs.

adding the missing blank fixes the problem.

Reproducible: Always

Steps to Reproduce:
1. # emerge =app-forensics/chkrootkit-0.47
2. # chkrootkit

The duplicate bug contains a patch that fixes the problem.  Something in the
code trips a bug with the -O2 gcc optimization flag.

Better show changes as a patch - easier to review.
And, please, attach changes to bugzilla - then we do not loose them.

BTW, could somebody provide test case as this crash is not reproducible on my
system?

Although I failed to reproduce the issue, patch seems to be correct. Applied.
Reopen bug if problem is still reproducible in >=chkrootkit-0.48-r1 and attach
wtmp files so I could reproduce crash too. Thanks you bazbar for report and 
Sourav Mandal for the fix.
