Latest update crashes vpnc
I updated my system yesterday, now vpnc crashes:

Re: Latest update crashes vpnc
I built from source and made the following change to fix the crash, which was apparently an assert.
Index: vpnc.c
===================================================================
--- vpnc.c (revision 550)
+++ vpnc.c (working copy)
@@ -1203,7 +1203,7 @@
assert(a->af == isakmp_attr_16);
assert(a->u.attr_16 == IKE_LIFE_TYPE_SECONDS || a->u.attr_16 == IKE_LIFE_TYPE_K);
assert(a->next != NULL);
- assert(a->next->type == IKE_ATTRIB_LIFE_DURATION);
+ /* assert(a->next->type == IKE_ATTRIB_LIFE_DURATION); */
if (a->next->af == isakmp_attr_16)
value = a->next->u.attr_16;Not sure why it is needed. VPN works flawlessly again.

Re: Latest update crashes vpnc
You should certainly report that upstream - blocking an assertion is by no means a fix to anything.
Either the assumption is wrong or there's a bug caught by the assert that should be fixed.
