Scoped enums in switch

Hi,

I can't seem to get scoped enums to work as case labels in a switch block in the Linux compiler. The following compiles fine on Windows but failed on Linux:

[cpp]

#include <iostream>


int main ( int argc, char * argv [] ) {

  enum class scoped_enum {

    AA, BB, CC, DD

  };

  scoped_enum test (scoped_enum::AA);

  switch (test) {

  case scoped_enum::AA:

    std::cout << "AA" << std::endl;

    break;

  case scoped_enum::BB:

    std::cout << "BB" << std::endl;

    break;

  case scoped_enum::CC:

    std::cout << "CC" << std::endl;

    break;

  case scoped_enum::DD:

    std::cout << "DD" << std::endl;

    break;

  }

  return 0;

}

[/cpp]

Is this a compiler bug, or am I doing something wrong (thought it would be a common issue but I couldn't find any other threads about it)?

Thanks,

Ben

Ah, thanks Sergey. That's it; looks like I missed that thread when I was searching.

I'll just use an unscoped enum until it's fixed.

Cheers,
Ben
