+Summary: [GMCS] Compile error on code that is incorrect which csc compiles
+
+Description of Problem:
+
+The following little code snippet
+
+object d;
+object q;
+
+...
+
+q = (double?)((decimal) d);
+
+produces an error "cannot convert from decimal to double?" on gmcs, csc
+compiles it.
+
+From the standard:
+
+"For these reasons, no implicit conversions exist between the floating
+point types and decimal"
+" -- an implicit conversion exists from any non-nullable value type to a
+nullable form of that type"
+
+Strictly said, that makes (double?)decimalvalue    an error _if_ the
+conversion needs to convert to double first.
+
+gmcs seems to be correct, this is only a "differs from csc" bugreport.
