<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public static class IEnumerableTransform {
public static IEnumerable<TOut> Transform<TOut> (this IEnumerable<int>
input, EmitterFunc<TOut> rule) {
foreach (var v in input) {
TOut output;
rule (out output);
yield return output;
}
}
public static EmitterFunc<TOut> Emit<TOut> (TOut result) {
return delegate (out TOut output) {
output = result;
};
}
public delegate void EmitterFunc<TOut> (out TOut output);
public static void Main () {
IEnumerable<int> arr = new int [10];
Console.WriteLine (arr.Transform<char> (IEnumerableTransform.Emit<char>
('t')).ToArray ());
}
}
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
When running the code compiled by dmcs, both the mono and the MS runtime crash,
mono --verify reports:
Unhandled Exception: System.BadImageFormatException: Error verifying
IEnumerableTransform/<Emit>c__AnonStorey1`1:<>m__0 (TOut&): Invalid generic
type (!!!!0) (argument out of range or method is not generic) at 0x0007
This happens with both HEAD and 2.10.
