expected expression (ccls 4) when declaring a variable directly underneath `case`

Observed behavior

ccls is telling me that a variable declaration is not allowed underneath a case statement.

However, it is okay if the variable declaration comes after something like an if:

Expected behavior

There isn no error reported

Steps to reproduce

  int func(){  
      int a;  
      switch (a) {  
          case 1:
              if(1){}
              int b;
          case 2:
              int c;  // Expected expression (ccls 4)
      }                                                            
      return 0;                                                    
  }
