[issue39001] possible problem with 64-bit mingw DECREF

[Dave Lawrence]

Dave Lawrence <mail.dave.lawrence at gmail.com> added the comment:

by redefinining the Py_DECREF macro in my application:

#define  Py_DECREF(op) do { if (--op->ob_refcnt == 0) fprintf(stderr, "DECREF %s %d %p %d %s %p\n", __FILE__, __LINE__, op, Py_SIZE(op), Py_TYPE(op)->tp_name,Py_TYPE(op)->tp_dealloc );  fflush(stderr); } while(0)

this outputs lines like this:

DECREF vardef_file.cc 1601 0000000009F3C728 0 generator 0000000000000000

which appears to be showing the tp_dealloc is a null pointer.
