Let the contents of the file "tmp.el" be:
(defun test (files)
(and t (string-match 1))
(and t (string-match 1 2)))
Then input M-x byte-compile-file RET tmp.el RET
*Compile-Log* buffer shows:
In test:
tmp.el:3:11:Warning: string-match called with 1 argument, but requires 2-3
The warning must indicate the line 2.

It's a known issue that the byte compiler cannot report the lines for
warnings and errors accurately. See, for example, bug#24449,
bug#24128, etc.
