Bug ID: 126974
Summary: truncating caret output when COLUMNS lower than
diagnostic length regardless of flags
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: diagnostics
Assignee: dmalcolm at redhat dot com
Reporter: waffl3x at gcc dot gnu.org
Target Milestone: ---
Created attachment 65379
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=65379&action=edit
Output with various values of COLUMNS
The line with the error ends before column 90, and the diagnostic at its
longest ends before column 100. (I believe that makes them 89 and 99
columns wide but I'm being precise in case I've got it wrong somehow.)
COLUMNS=98 does not truncate the output.
COLUMNS=97 truncates the output by 1 character
The result is not changed by -fmessage-length=0.
```
int f(int
*ASTARTaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
int *b)
{
return
ASTARTaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
b;
}
```
