+Summary: ves_icall_MonoType_get_DeclaringMethod abort during compilation
+
+The following testcase fails to compile with Mono 1.1.13's gmcs, the
+runtime aborts.
+MethodClass defines a method 'Get' with an out parameter.
+GenericMethodClass provides a similar method, it is generic however.
+Invoking 'Get' on an instance of GenericMethodClass (FAILURE must be
+defined) causes the runtime to abort. If the target method is not generic,
+compilation succeeds. Compiling the same testcase with Microsoft's csc
+succeeds aswell.
+
+using System;
+
+public class TestClass
+{
+}
+
+public class MethodClass
+{
+  public void Get(out TestClass test)
+  {
+    test = new TestClass();
+  }
+};
+
+public class GenericMethodClass
+{
+  public void Get<T>(out T test) where T : new()
+  {
+    test = new T();
+  }
+};
+
+public class Test
+{
+  public static void Main(string[] args)
+  {
+    TestClass unassigned;
+
+#if FAILURE
+    GenericMethodClass cl = new GenericMethodClass();
+#else
+    MethodClass cl = new MethodClass();
+#endif
+
+    cl.Get(out unassigned);
+  }
+};
+
+Steps to reproduce the problem:
+1. gmcs -define:FAILURE testcase.cs
+
+Actual Results:
+
+** ERROR **: file icall.c: line 2394
+(ves_icall_MonoType_get_DeclaringMethod): assertion failed: (method)
+aborting...
+Aborted
+
+Expected Results:
+
+Successful compilation
+
+How often does this happen?

+100 out of 100 times
