It still their bug, not ours. Also pine is not even free or open software.
But PPC has the same issue as ia64 and nobody complained about this until now.
The main use need of -fno-omit-frame-pointer is with __builtin_frame_address which needs the frame
pointer, otherwise it goes crazy. (See PR 8355).
on PPC, there is no register that is almost always the frame pointer (well in GCC there is but really it
does not have to be). And the frame pointer keeps no extra information that is not kept with the stack
pointer.
