Bug 462108 – net-dialup/pptpd-1.3.4-r3 crashes when calling ppp with unrecognized option

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Klemen Mihevc 2013-03-17 22:17:54 UTC]

This is probably since it was compiled with gcc 4.7+ anyway, when trying to connection to VPN it crashes and you get in logs something like this:

Mar 17 22:57:02 mih pppd[15350]: unrecognized option '˙˙ţ˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙'

found explanation and solution here: https://bbs.archlinux.org/viewtopic.php?id=140838 and attaching patch...

Reproducible: Always

[Comment 3 Heiko Steindl 2013-06-12 08:14:07 UTC]

same problem on my system with gcc-4.7.3 and ppp-2.4.5-r3 pptp-1.3.4-r3.

Error when compiling with gcc-4.7.3 after starting the connection on the client:
pppd[]: unrecognized option 'ÿÿÿþÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ.....' or pppd[]: unrecognized option '?????????....'

After recompiling with gcc-4.6.3 it works and the clients can connect.
