--- Comment #16 from Jonny Grant <jg at jguk dot org> --- Hello! Checked 23 Feb trunk g++ (Compiler-Explorer-Build) 9.0.1 20190223 (experimental) comment 9 test case #line 0 does not give an error Original test case still shows negative line numbers <source>:-737418241:2: warning: #warning second [-Wcpp] <source>:-737418240:7: warning: line number out of range Same for comment 5 test case Could the "line number out of range" specify what the max line number supported is perhaps?
