When calling a function with a single argument which is an unparenthesized generator expression the end column for the AST node is incorrect, it is one greater than the start of the function call parentheses where I assume it should be one past the closing parentheses.

This call:

func(i for i in range(3))

Generates the following node for the generator expression (line:col_offset -> end_line:end_col_offset):

<_ast.GeneratorExp object at 0x7f3ba61f78c0> .. 1:4 -> 1:5

I am on 3.8.1 and you are right this is the same as #39235 so please disregard.
