Possibly also related, so I though I'd mention it here (sorry if this is
hijacking the ticket, seems difficult to tell). We're also seeing None values
in f_lineno in Cython's test suite with 3.11a5:
File "<doctest line_trace.run_trace[2]>", line 1, in <module>
run_trace(py_add, 1, 2)
^^^^^^^^^^^^^^^^^^^^^^^
File "tests/run/line_trace.pyx", line 231, in line_trace.run_trace
(line_trace.c:7000)
func(*args)
File "tests/run/line_trace.pyx", line 60, in line_trace.trace_trampoline
(line_trace.c:3460)
raise
File "tests/run/line_trace.pyx", line 54, in line_trace.trace_trampoline
(line_trace.c:3359)
result = callback(frame, what, arg)
File "tests/run/line_trace.pyx", line 81, in
line_trace._create_trace_func._trace_func (line_trace.c:3927)
trace.append((map_trace_types(event, event), frame.f_lineno -
frame.f_code.co_firstlineno))
TypeError: unsupported operand type(s) for -: 'NoneType' and 'int'
https://github.com/cython/cython/blob/7ab11ec473a604792bae454305adece55cd8ab37/tests/run/line_trace.pyx
No generator expressions involved, though. (Much of that test was written while
trying to get the debugger in PyCharm to work with Cython compiled modules.)
There is a chance that Cython is doing something wrong in its own line tracing
code, obviously.
(I also remember seeing other tracing issues before, where the line reported
was actually in the trace function itself rather than the code to be traced. We
haven't caught up with the frame-internal changes yet.)
