From c03faa32f335f3fb7bc1bc8718dd1781781ef3dd Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Wed, 4 May 2011 15:42:50 -0500 Subject: Reduce duplicate signing debug code and fix logic condition We had a lot of similar looking code that we can collapse down into a function. This also fixes errors seen when turning on some gcc warnings and implicitly casting away the const-ness of the string. Free the list when we are done with it as well. Also, fix a logic error where we should be checking with &&, not ||.
