Any idea what to do about the following assertion failure?
../../src/gdb/frame.c:2083: internal-error: get_frame_type:
Assertion `frame->unwind->type != UNKNOWN_FRAME' failed.
Here are the details:

(top gdb) p frame->unwind
$1 = (struct frame_unwind *) 0x82ad184
(top gdb) p *frame->unwind
$2 = {type = UNKNOWN_FRAME, this_id = 0x81406fc <legacy_saved_regs_this_id>,
prev_register = 0x8140424 <legacy_saved_regs_prev_register>}
(top gdb) p legacy_saved_regs_unwind
$3 = (struct frame_unwind *) 0x82ad184
AFAICT, we're going to see this problem whenever frame_unwind_find_by_pc()
returns legacy_saved_regs_unwind.
