Oh, I didn't understand that the regression was introduced by the revision b9c9691c72c5. The purpose of this revision was to *reduce* the memory usage of the C stack!?
It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs(). PyObject_CallFunctionObjArgs() allocates 4O bytes (5*sizeof(PyObject*)) on the stack.
At least, I can say that when the crash occurs, _PyObject_FastCallDict() is not the gdb backtrace. |
