Subject: 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;
}

Thanks for the bug report, but it does not contain enough information
for us to do anything. I assume you are referring to C mode. However,
if I paste your snippet into a fresh foo.c and call M-x
c-syntactic-information-on-region, I get the following:
switch (x) /* ((topmost-intro 1)) */
{ /* ((substatement-open 1)) */
case 'a': /* ((case-label 42)) */
case 'b': /* ((case-label 42)) */
x = 1; /* ((statement-case-intro 117)) */
y = 2; /* ((statement 157)) */
break; /* ((statement 203)) */
} /* ((block-close 42)) */
As you can see, the snippet is correctly parsed.
Please provide an exact, step-by-step recipe for reproducing this bug,
starting with `emacs -Q'.
