Wrong IL generated for storing value in a local variable.

Source code

class Program
{
    static void Main(string[] args)
    {
        int add = Add(20, 10);
        int sub = Subtract(20, 10);
        int multiply = Multiply(20, 10);
        int divide = Divide(20, 10);
        // Issue here
        int modulo = Modulo(20, 10);
    }

    static int Add(int i, int j) => i + j;

    static int Subtract(int i, int j) => i - j;

    static int Multiply(int i, int j) => i * j;

    static int Divide(int i, int j) => i / j;

    static int Modulo(int i, int j) => i % j;
}

Steps to reproduce

1. Compile the above source code into a DLL.
2. Run dotnet ildasm on the DLL.

Expected IL

IL_0032: stloc.s V_4

Actual IL

IL_0032: stloc.s class V_4

Error
When running ILAsm : MSIL.il(60) : error : syntax error at token 'class' in: IL_0032: stloc.s class V_4
Works well with traditional ILDAsm.
