Proposed fix

I guess the problem is in improper initialization of the call structure, attached patch should fix it.

Comment 13 Jaroslav Škarvada 2015-01-20 15:57:36 UTC 
I quick scanned the bug report and cannot find anything problematic (regarding Fedora contributors privacy), thus making the bug report public to be accessible by upstream.
Comment 14 ssabchew 2015-01-21 01:04:03 UTC 
Thanks - I updated to new pptp version - so far so good - no crashes.
Comment 15 Jaroslav Škarvada 2015-01-21 10:52:15 UTC 
Reopened, after discussion with upstream.

The problem is very probably still unfixed.

ssabchew: Could you remember what you did to trigger the problem? I am unable to reproduce the problem locally.
