From a53ebcf5460882ca75a41bffca1cdd27af08c83e Mon Sep 17 00:00:00 2001 From: Russell Bryant Date: Fri, 27 Apr 2007 16:14:11 +0000 Subject: [PATCH] If no variables were passed into pbx_substitute_variables_helper_full(), then don't even bother creating a temporary bogus channel, since that is only for allowing certain functions to operate on the variables as if they were on a channel. Most importantly, this fixes a crash.
