[issue40638] input() with malformed input stream triggers assertion failure

[Maxwell Bernstein]

New submission from Maxwell Bernstein <tekk.nolagi at gmail.com>:

builtin_input_impl does multiple attribute lookups in a row assuming they will succeed, but part of attribute lookup assumes that there is no pending exception.

I propose doing the lookups one by one and checking for an error after each. There is an upcoming patch.
