Public bug reported:
The code below runs fine on MS .net, but fails in mono in ubuntu. I've
compiled with both MS C# compiler, csc.exe, and with mono's mcs, both
compiles fine, but mono cannot run the applications.
Mono gives this error when running the mcs compiled code:
Unhandled Exception: System.InvalidProgramException: Invalid IL code in
Tester:Main (string[]): IL_0058: stloc.s 5
And a almost identical when running the csc compiled one:
Unhandled Exception: System.InvalidProgramException: Invalid IL code in
Tester:Main (string[]): IL_0057: stloc.3
..
As I said, when executed on MS Windows in MS .net the csc compiled code runs
fine.
Here is the C# code that causes the errors:
/* This class works fine */
public class Works {
private double val;
public double this[int i, int j] {
get { return val; }
set { val = value; }
}
public Works(double val)
{ this.val = val; }
}
/* Same code as struct breaks */
public struct Breaks {
private double val;
public double this[int i, int j] {
get { return val; }
set { val = value; }
}
public Breaks(double val)
{ this.val = val; }
}
public class Tester {
public static void Main(string[] args)
{
System.Console.WriteLine("This works");
Works w = new Works(3.0);
w[0, 0] += 3.0;
System.Console.WriteLine("This breaks");
Breaks b = new Breaks(3.0);
b[0, 0] += 3.0;
}
}
