Bug ID: 89936 Summary: wrong punctuation in tree-profile.c Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: translation Assignee: unassigned at gcc dot gnu.org Reporter: roland.illig at gmx dot de Target Milestone: --- error ("invalid regular expression '%s' in %<%s%>", Please implement a GCC-specific linter that prohibits single quotes in messages. These should either be %' if they are meant as punctuation, or %q if they enclose a placeholder. Do not just fix this single typo. There are more to come, and they will never end. I've seen far too many now. Just write a little linter. It's not that difficult.
