Comment (by howarth@…):

 The origin of the gcj problems with darwin9 and earlier is that the
 unwinder derived from libgcc doesn't grok[[BR]]
 the epilogue notes in the eh_frames emitted starting with FSF gcc
 4.3...[[BR]]

 A patch to suppress these eh_frame epilogue notes on darwin9 and earlier
 was proposed in this thread...[[BR]]

 but never completed. Note these epilogue notes fortunately aren't
 problematic on darwin10 and later because they[[BR]]
 are running the compatibility unwinder from libSystem instead.[[BR]]
