We use g++ to compile our big project and we use many 3rd party libraries and frameworks inside(like Qt or Poco). Some of these frameworks generate many warnings, so we use flag isystem to mark them as system to suppress 3dparty warnings. But it seems not all warnings suppressing by this flag. As result we have dozens 3dparty warnings in our project - they very very garbaging  build logs. I found similar issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100570 but it's still even in UNCONFIRMED status - my opinion all just forgot about this issue.
