>Description:
The following class compiles, but it should fail
because of a duplicate switch block.

class T1410d1 {
    void foo(int i) {
        switch (i) {
            case 0:
            case 0:
        }
    }
}


One can even get the compiler to core
dump by adding another a case label:


class T1410d1 {
    void foo(int i) {
        switch (i) {
            case 0:
            case 1:
            case 0:
        }
    }
}
>How-To-Repeat:
Compile with "gcj -C T1410d1.java".
