Subject: Loss of location in (library) code
Date: Sat, 14 Nov 2020 20:26:13 +0100	[thread overview]
Message-ID: <20201114192613.GA4924@air> (raw)

As discussed on #guile, we tried for a "possibly unbound variable" warning, on Guile 3.0.4:

When the offending form is somewhere in a RnRS module or Guile library, the warnings give inconsistent line numbers. For instance:

(library (test)
 (export f)
 (import (rnrs))
 (define (f x)
  (if x
   (cons x 3)
   (IS-UNBOUND x))))

produces "4:1: warning: possibly unbound variable `IS-UNBOUND'", the warning is located on the (define) whereas

; Line 1
; Line 2
; Line 3
(define (f x)
 (if x
  (cons x 3)
  (IS-UNBOUND x)))

produces "7:2: warning: possibly unbound variable `IS-UNBOUND'", the warning is located correctly.
