-fsanitize=shift compile error

[Mateusz Tabaka <tab.debugteam@xxxxxxxxx>]

Hi,

I'm trying to compile this file:
int main()
{
        int a = 0;
        switch (a)
        {
        case (4 << 29):
                break;
        }
        return 0;
}

and I get this error:
./host-x86_64-pc-linux-gnu/gcc/cc1 test.c -quiet -fsanitize=shift
test.c: In function ‘main’:
test.c:6:2: error: case label does not reduce to an integer constant
  case (4 << 29):
  ^~~~

If I remove "-fsanitize=shift" (or change the expression to be less than 
2^31) I'm able to compile above code without issues.
It is expected behavior or a known bug?

Thanks.
