[New-bugs-announce] [issue34125] Profiling depends on whether **kwargs is given

[Jeroen Demeyer]

New submission from Jeroen Demeyer <J.Demeyer at UGent.be>:

Enable profiling for C functions:

    >>> def prof(frame, typ, arg):
    ...     if typ.startswith("c_"):
    ...         print(arg, typ)
    >>> import sys; sys.setprofile(prof)

and notice how profiling depends on **kwargs:

    >>> list.append([], None)
    <built-in method append of list object at 0x7f52da2a2dd0> c_call
    <built-in method append of list object at 0x7f52da2a2dd0> c_return
    
    >>> list.append([], None, **{})

There is no specification of what should be profiled and what not, so it's not clear what is the "correct" behavior. For the record: in Python 3.6, neither of these were profiled.
