From 7716aef138e8029357a7b3dc6a73b41f4de4b0ad Mon Sep 17 00:00:00 2001 From: Christopher Tate Date: Tue, 2 Apr 2013 14:00:27 -0700 Subject: Uploaded native crash dumps do not include memory contents Also fixed the LOG() macro to actually write to the log again, tracking the change in _LOG() argument semantics.
