clspv crash when switching on an enum

[gnl21]

Trying to compile:

typedef enum test_t
{
  NONE = 0,
  ONE  = 1
} test_t;


__kernel void switch_test ()
{
  test_t t;

  switch(t)
  {
    default:  break;
  }
}

Results in a crash:

IsSupportedType lacks support for QualType: __private test_t
Type not covered by IsSupportedType.
