[Deborphan-devel] Bug#741282: free(): invalid pointer: with " \n" line in keep file

[Kevin Mitchell]

Package: deborphan
Version: 1.7.28.8
Severity: normal

When running deborphan with no arguments
$ deborphan
*** Error in `deborphan': free(): invalid pointer: 0x0000000000ab9401 ***

I traced the problem down to the line " \n" in my
/var/lib/deborphan/keep file. I'm not sure how such a line found its
way in there, but seeing as how (to my knowledge) this file has only been edited by
deborphan itself, I think this case should be handled more gracefully.

The offending free is at keep.c:107. I think the problem is that
100:line2 += strspn(line2, " \t");
is shifting the pointer forward by one character which is consequently not freeable.
