Bug ID: 90477
Summary: negative line numbers should not be displayed
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jg at jguk dot org
Target Milestone: ---
Using godbolt trunk
gcc shows negative numbers, I don't know if it is any better to put a ceiling,
at least if the line number was stuck at 2147483646 that might be better than
wrapping to negative.
Although making line numbers 64bit might be a nicer solution.
