New submission from Marc-Andre Lemburg <m...@egenix.com>:
In Python 3.10, it seems that top-level frames generated by running exec() have
their f_lineno attribute set to None.
inspect.getframeinfo() tries to build context lines and fails on this line in
such a case:
start = lineno - 1 - context//2
because lineno is None.
It's not clear whether this is a bug in inspect or the way such frames get
their f_lineno attribute initialized.
The same code works just fine in Python 3.9.
