Isn't that what FRAME_META_TYPE_PT_REGS is for? Maybe it can just tell kunwind_stack_walk() to set a bit in kunwind_state which tells kunwind_next_frame_record_meta() to quit the unwind early for the FRAME_META_TYPE_PT_REGS case. That also has the benefit of stopping the unwind as soon as the exception is encounterd. -- Josh
