Another user experienced a similar problem:

So this can't be caused by any operation directly related to pptp since I didn't manipulate it at all. All I know is that I was listening to online music using flashplayer and it suddenly lost connection. Then pptp is reported crashed.

Comment 12 James Cameron 2015-01-22 00:44:21 UTC 
In your /var/log/messages we see that the triggering event was a connection reset by peer, which is the PPTP server.

The rest of the log, including the SIGSEGV, was a cascade from this trigger.

A possible cause of SIGSEGV was fixed upstream just now, but this won't fix your PPTP server.
