           Summary: [regression] experimental mcs fails to import
                    attributed List<object> field

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:

The attached example fails to compile on mono git-master experimental (*).

Reproducible: Always

Steps to Reproduce:
rm -f 1.dll 2.dll dep.dll
gmcs /t:library DepAttribute.cs /out:dep.dll
gmcs /t:library /r:dep.dll Foo.cs  /out:1.dll
gmcs /t:library /r:1.dll Bar.cs /out:2.dll
(or just run make, there is a Makefile)

Actual Results:  
Bar.cs(7,21): error CS0584: Internal compiler error: Cannot import field
`FooN.Foo.MyList' referenced in assembly `1, Version=, Culture=neutral,
Bar.cs(7,17): error CS0266: Cannot implicitly convert type `object' to
`FooN.Foo'. An explicit conversion exists (are you missing a cast?)
Bar.cs(8,15): error CS1061: Type `FooN.Foo' does not contain a definition for
`MyList' and no extension method `MyList' of type `FooN.Foo' could be found
(are you missing a using directive or an assembly reference?)

Expected Results:  
It should build ok.
Mono 2.8.1 and 2.6.7 build it.

(*) mono git-master experimental, I copied mcs/class/lib/basic/mcs.exe into
