            Bug ID: 378677
           Summary: returning-void-expression false positive
           Product: clazy
           Version: unspecified
          Platform: unspecified
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: oktal3700 at gmail.com
                CC: smartins at kde.org
  Target Milestone: ---

The returning-void-expression warning is spuriously generated by any code that
returns a braced-initializer, such as the following testcase:

int test()
{
    return {};
}

In Clang's AST, before semantic analysis, the type of a braced-initializer is
void.

The AST visitor should skip the warning if the return value is-a InitListExpr.
