            Bug ID: 91746
           Summary: Bogus error due to a type and variable with the same
                    name
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: david.bolvansky at gmail dot com
  Target Milestone: ---

GCC fails to compile:

struct pixel {
    int x;
    int y;
};

struct master {
    pixel pixel;
};


<source>:9:11: error: declaration of 'pixel master::pixel' changes meaning of
'pixel' [-fpermissive]

    9 |     pixel pixel;

      |           ^~~~~

<source>:3:8: note: 'pixel' declared here as 'struct pixel'

    3 | struct pixel {

      |        ^

Clang, ICC, MSVC - compiles it just fine.
