[New-bugs-announce] [issue34495] excess_args asserts if args == nullptr

[Tatyana]

New submission from Tatyana <tatyana at synopsys.com>:

Since version 3.7 PyTuple_GET_SIZE performs assert(PyTuple_Check(args)); Due to this change, object_new and object_init cannot be called with args == nullptr.

Such behavior breaks existing user's code, particularly a code generated with Swig.
