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.
