I could be naughty as not using:
https://docs.python.org/3/c-api/reflection.html#c.PyFrame_GetLineNumber
<https://docs.python.org/3/c-api/reflection.html#c.PyFrame_GetLineNumber>
int f_lasti; /* Last instruction if called */
/* Call PyFrame_GetLineNumber() instead of reading this field
directly. As of 2.3 f_lineno is only valid when tracing is
active (i.e. when f_trace is set). At other times we use
PyCode_Addr2Line to calculate the line from the current
bytecode index. */
int f_lineno; /* Current line number */
int f_iblock; /* index in f_blockstack */
char f_executing; /* whether the frame is still executing */
PyTryBlock f_blockstack[CO_MAXBLOCKS]; /* for try and loop blocks */
PyObject *f_localsplus[1]; /* locals+stack, dynamically sized */
In other words, I am accessing f_lineno directly which may not work correctly
now.
Have to remember some of this code was written a very very long time ago. :-)
