            Bug ID: 93168
           Summary: Error messages are full of control code garbage
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

For example,

nestfunc-1.c: In function 'f':
nestfunc-1.c:22:1: warning: control reaches end of non-void function
[]8;;https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wreturn-type-Wreturn-type]8;;]

(and it doesn't show the warning option, either, any more).

This stuff should not be enabled by default.
