23.1; syntactic analysis incorrect
--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;
}
