Compiler crashes with generic parameter arrays in constructors

Binary package hint: mono

If you have a class with a default constructor, a constructor that accepts a parameter array of a generic type, and one that accepts a parameter array of a non-generic type, and a call to the constructor with no arguments then the compiler crashes.

If the default constructor did not exist this would create an ambiguity, but the compiler also crashes rather than reporting this. MS compiles the code and calls the parameter-less default constructor.

I've attached a code file that illustrates this problem, which requires references to System and System.Core assemblies.

The workaround is to replace the generic constructor to include one mandatory element before the parameter array.

This bug appears to be unfixed even in the latest versions of mono.
