What's your issue about?

if last line in a function is a comment I get this

x: public(uint256)

@external
def foo(ix: uint256):
    bar: uint256 = self.x
    #?? throws >> ValueError: start (7,7) precedes previous end (8,0)

How can it be fixed?

no idea

Appears #1161 has come back to life

I figured out why I was not getting an error in the previous issue. My text editor inserts a newline at the ends of files, and when the newline is there there is no issue. Here's a minimal example:

(vyper) charles@cmc-thinkpad ~/vyper $ xxd repros/2410.vy 
00000000: 2320 6661 696c                           # fail
(vyper) charles@cmc-thinkpad ~/vyper $ vyper -f ir repros/2410.vy 
ValueError: start (1,6) precedes previous end (2,0)

(vyper) charles@cmc-thinkpad ~/vyper $ vim repros/2410.vy # add newline
(vyper) charles@cmc-thinkpad ~/vyper $ xxd repros/2410.vy 
00000000: 2320 7375 6363 6573 730a                 # success.
(vyper) charles@cmc-thinkpad ~/vyper $ vyper -f ir repros/2410.vy 
seq

However, this should have been fixed in #1720 ... not sure why this is cropping up again.
