    py-cffi: updated to 1.14.0

    v1.14

    ffi.dlopen() can now be called with a handle (as a void *) to an already-opened C library.
    CPython only: fixed a stack overflow issue for calls like lib.myfunc([large list]). If the function is declared as taking a float * argument, for example, then the array is temporarily converted into a C array of floats窶派owever, the code used to use alloca() for this temporary storage, no matter how large. This is now fixed.

    The fix concerns all modes: in-line/out-of-line API/ABI. Also note that your API-mode C extension modules need to be regenerated with cffi 1.14 in order to get the fix; i.e. for API mode, the fix is in the generated C sources. (The C sources generated from cffi 1.14 should also work when running in a different environment in which we have an older version of cffi. Also, this change makes no difference on PyPy.)

    As a workaround that works on all versions of cffi, you can write lib.myfunc(ffi.new("float[]", [large list])), which is equivalent but explicity builds the intermediate array as a regular Python object on the heap.
    fixed a memory leak inside ffi.getwinerror() on CPython 3.x.
