The 3105 is the offset into __mixer_init of the instruction that tried to
call __Frame_Begin__. The -127389677 means that __mixer_init jumped into
never-never land, missing __Frame_Begin__ by a country klick. You probably
either invoked a method on an address that isn't that of an object, after
a bad cast or through an uninitialized pointer, or else you have a bug in
a jump table of some kind, likely an off-by-1 error involving a call
through a function pointer one past the end of the table...
