Comment (by larryv@…):

 I know what’s going on. The crash log looks uncomfortably familiar…
 {{{
 Exception Type:        EXC_BAD_ACCESS (SIGSEGV)
 Exception Codes:       EXC_I386_GPFLT

 Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

 …because this is my old friend, the [[comment:35:ticket:44596|Libtool
 MACOSX_DEPLOYMENT_TARGET bug]].

 I’ve attached a [[attachment:yosemite-symbol-lookup.patch|preliminary
 patch]]. Could you try it?
