Not worth fixing: j is never used in that function, and so the compiler more than likely optimizes this dead code out entirely.

It is not entirely clear to me that this is a

Much safer to avoid writing undefined code than just
guess the compiler does something sensible with it.
It seems worth fixing to me.

Description of problem: I just tried to compile package sane-backends-1.0.14-2 from Redhat Fedora Core 3 Test 1.

Actual results: Expected results: Additional info:
