Test program

We expect a System.OverflowException when initializing an array with a negative size.  Mono ends up throwing a System.OutOfMemoryException instead.  This only occurs on 64-bit Mono.
Comment 1 Zoltan Varga 2016-09-15 15:07:10 UTC
This is a 64 bit only problem, it happens because the JIT passes a 32 bit int to the managed allocator method which takes a native int, and we don't do sign extension.
