            Bug ID: 113760
           Summary: gcc rejects valid empty-declaration in pedantic mode
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tanksherman27 at gmail dot com
  Target Milestone: ---

In https://github.com/openjdk/jdk/pull/17687#issuecomment-1926154325 we
discovered a possible g++ bug where g++ rejects empty semicolons in pedantic
mode, this is rather evident in code like

#define DEBUG_ONLY(code) code;

DEBUG_ONLY(foo());

which will fire a -Werror warning even in C++11 and above, where such empty
declarations are allowed
