[New-bugs-announce] [issue2895] Crash in ParseTupleAndKeywords when passing byte string keywords

[Stefan Behnel]

New submission from Stefan Behnel <scoder at users.sourceforge.net>:

Using 3.0a5, the following code crashes in vgetargskeywords (getargs.c:1542)

  >>> d = {b"encoding": "abc"}
  >>> str(b"abc", **d)

It should raise a TypeError instead, i.e. line 1535 should read

  if (!PyUnicode_Check(key)) {

instead of

  if (!PyString_Check(key) && !PyUnicode_Check(key)) {
