Nosying Benjamin Peterson who knows frame_setlineno (issue 14612) and nosying
Jesús Cea Avión. Hoping they don't mind.

This problem occurs also when setting f_lineno from an exception debug event.

One may crash the interpreter (or get a "SystemError: unknown opcode") when the
return debug event is one that handles a yield statement.  For example the
following test causes a segmentation fault on python 3.3.0:

$ python /tmp/jump.py
> /tmp/jump.py(7)<module>()
-> for i in gen():
(Pdb) step
--Call--
> /tmp/jump.py(1)gen()
-> def gen():
(Pdb) step
> /tmp/jump.py(2)gen()
-> for i in range(1):
(Pdb) step
> /tmp/jump.py(3)gen()
-> yield i
(Pdb) step
--Return--
> /tmp/jump.py(3)gen()->0
-> yield i
(Pdb) jump 2
> /tmp/jump.py(2)gen()->0
-> for i in range(1):
(Pdb) step
> /tmp/jump.py(8)<module>()
-> lineno = 8
(Pdb) step
> /tmp/jump.py(7)<module>()
-> for i in gen():
(Pdb) step
--Call--
> /tmp/jump.py(2)gen()->0
-> for i in range(1):
(Pdb) step
