Bug report
Originally found in#110782 by@mxschmitt and@JelleZijlstra
This is the reproducer:
/*[clinic input]null_or_tuple_for_varargs name: object *constraints: object covariant: bool = False[clinic start generated code]*/staticPyObject*null_or_tuple_for_varargs_impl(PyObject*module,PyObject*name,PyObject*constraints,intcovariant)/*[clinic end generated code: output=a785b35421358983 input=017dc120cb6e651b]*/{assert(name!=NULL);assert(constraints!=NULL);assert(covariant==0||covariant==1);Py_RETURN_NONE;}
When called withname=..., it crashes:
>>>import_testclinic>>>_testclinic.null_or_tuple_for_varargs('a')>>>_testclinic.null_or_tuple_for_varargs(name='a')Assertionfailed: (constraints!=NULL),functionnull_or_tuple_for_varargs_impl,file_testclinic.c,line1148.[1]30808abort ./python.exe
I have a PR ready with the fix.
