The purpose of PyErr_SyntaxLocationEx() function (added in 00e4ce31d404) was setting the offset attribute of raised syntax error to specified value. But this never worked as expected. The offset attribute is set to integer value in Python/errors.c:1067, but then replaced with None in Python/errors.c:1083.

Here is a patch that makes PyErr_SyntaxLocationObject() setting correct offset.

Looks good apart from one quirky test case, see Reitveld

Good catch Martin! Opened issue28936 for that quirky test.

Hi Serhiy, there are two commented-out lines in (only in 3.5)

+        #with self.assertRaises(AssertionError):
+            #support.check_syntax_error(self, "x=1")

Ah, it was a remnants of backporting to 3.5. Commented-out lines are used in 3.6. The line above these lines was used in 3.5. Test is passed with both variants. I commented out the 3.6 variant, but forgot to remove it (or remove old 3.5 variant and keep 3.6 variant). Do you think I should remove commented out lines, or left the code as is?
