STINNER Victor <vstin...@python.org> added the comment:
Windows 64-bit emits a compiler warning on this line:
int len = PyBytes_GET_SIZE(f->f_code->co_code)/sizeof(_Py_CODEUNIT);
Warning:
D:\a\cpython\cpython\Objects\frameobject.c(400,1): warning C4267:
'initializing': conversion from 'size_t' to 'int', possible loss of data
[D:\a\cpython\cpython\PCbuild\pythoncore.vcxproj]
Either the code should be rewritten to to Py_ssize_t, or the result should be
downcasted to int.
Technically, it seems possible to create a code object larger than INT_MAX
instructors: PyCode_New() has no limit on the bytecode length.
