+Summary: parser bug in mcs with expressions that return a delegate
+
+Description of Problem:
+mcs seems to have a problem with expressions that return a delegate.
+
+Steps to reproduce the problem:
+1. Compile the following code:
+
+using System;
+
+delegate void foobar (int i);
+
+class Tester {
+ static void foo (int i)
+ {
+ Console.Out.WriteLine ("foo got " + i);
+ }
+
+ static void bar (int i)
+ {
+ Console.Out.WriteLine ("bar got " + i);
+ }
+
+ public static void Main ()
+ {
+ foobar foo = new foobar (Tester.foo);
+ foobar bar = new foobar (Tester.bar);
+ ((1 == 1) ? foo : bar) (2);
+
+ //foobar baz = ((1 == 1) ? foo : bar);
+ //baz (2);
+ }
+}
+
+
+Actual Results:
+syntax error, expecting ASSIGN OP_MULT_ASSIGN OP_DIV_ASSIGN
+OP_MOD_ASSIGN OP_ADD_ASSIGN OP_SUB_ASSIGN OP_SHIFT_LEFT_ASSIGN
+OP_SHIFT_RIGHT_ASSIGN OP_AND_ASSIGN OP_XOR_ASSIGN OP_OR_ASSIGN
+ternaryif.cs(20) error CS1002: Expecting `;'
+Compilation failed: 1 error(s), 0 warnings
+
+Expected Results:
+Compilation succeeded
+
+How often does this happen?
+Always.
+
