/ 6g accepts the program below even though it is syntactically incorrect:
/ Each statement in the list of statements for each case clause must be
/ terminated with a semicolon. No semicolon is present for the labeled
/ statements and because the last token is a colon ":", no semicolon is
/ inserted automatically.
/
/ Both gccgo and gofmt correctly refuse this program as is and accept it
/ when the semicolons are present.
/ This is a test case for issue 777 ( https://golang.org/issue/777 ).
package main
func main() {
switch 0 {
case 0:
L0: / ERROR "statement"
case 1:
L1: / ERROR "statement"
default:
/ correct since no semicolon is required before a '}'
goto L2
L2:
