--text follows this line--
A switch statement with two case labels, at least one of which is a
character constant, causes the syntactic analysis of the first statement
in the case block to be evaluated as statement-cont instead of
statement-case-intro.
I believe the line 'x = 1;' should be evaluated as statement-case-into,
but it is being evaluated as statement-cont.
 
switch (x)
  {
  case 'a':
  case 'b':
    x = 1;
  y = 2;
  break;
  }
