The reason for -fsanitize=address was an attempt to address the many issues clementine has with memory. For some reason that I can't put my finger on yet it behaves differently on different hardware. There is one definite issue with the enabling of the "save statistics in file tags when possible" see bug 1138261 I Leap:15.0 and 1 executing "clementine --help" intermittently cause a double free crash if the version is 1.3.1 or greater. The other current bug is Bug 1137785 I would appreciate some help.
