Bug ID: 67255 Summary: -Wpadded mixes apostrophes Product: gcc Version: 5.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: dilyan.palauzov at aegee dot org Target Milestone: --- gcc -Wpadded produces output like: file.h:10:3: warning: padding struct to align 'z' [-Wpadded] and like file.h:10:3: warning: padding struct to align āzā [-Wpadded] note the different apostrophe styles around z. When I try to compile a project with -Wpadded, I filter stderr through "sort -u", but some lines appear twice, because of the different apostrophes used by gcc.
