_PyArg_Parser holds static global data generated for modules by Argument Clinic. The _PyArg_Parser.kwtuple field is a tuple object, even though it's stored within a static global. In some cases the tuple is statically allocated and thus it's okay that it gets shared by multiple interpreters. However, in other cases the tuple is set lazily, allocated from the heap using the active interprepreter at the point the tuple is needed. This is a problem once that interpreter is destroyed since _PyArg_Parser.kwtuple becomes at dangling pointer, leading to crashes. It isn't a problem if the tuple is allocated under the main interpreter, since its lifetime is bound to the lifetime of the runtime. The solution here is to temporarily switch to the main interpreter. The alternative would be to always statically allocate the tuple. This change also fixes a bug where only the most recent parser was added to the global linked list.

"""
|

If this test failed, you probably added a new "format unit"
|
|
in Python/getargs.c, but neglected to update our poor friend
|
|
skipitem() in the same file. (If so, shame on you!)
|
|
|
|
With a few exceptions**, this function brute-force tests all
|
|
printable ASCII*** characters (32 to 126 inclusive) as format units,
|
|
checking to see that PyArg_ParseTupleAndKeywords() return consistent
|
|
errors both when the unit is attempted to be used and when it is
|
|
skipped. If the format unit doesn't exist, we'll get one of two
|
|
specific error messages (one for used, one for skipped); if it does
|
|
exist we *won't* get that error--we'll get either no error or some
|
|
other error. If we get the specific "does not exist" error for one
|
|
test and not for the other, there's a mismatch, and the test fails.
|
|
|
|
** Some format units have special funny semantics and it would
|
|
be difficult to accommodate them here. Since these are all
|
|
well-established and properly skipped in skipitem() we can
|
|
get away with not testing them--this test is really intended
|
|
to catch *new* format units.
|

*** Python C source files must be ASCII. Therefore it's impossible

to have non-ASCII format units.
