Why does Dictionary with a generic struct key blow the compiler up?
Its actually the new of the Dictionary that blows the compiler up.
using System.Collections.Generic;
namespace WWUtils.Math{
[System.Serializable]
struct Foo<T> {
}
public class Sparse3DMatrix<T> {
Dictionary<Foo<int>, T> valueStore = new Dictionary<Foo<int>, T>();
}
}
If I make the struct not a generic, it compilers fine. If I make the key a generic class, it compiles fine. If I remove the new it compiles fine.
But as written above, I get the following stack trace in the log:
-----CompilerOutput:-stdout--exitcode: 134--compilationhadfailure: True--outfile: Temp/Assembly-CSharp.dll
* Assertion at class.c:1727, condition `class->image->dynamic || field->offset > 0' not met
-----CompilerOutput:-stderr----------

This is still not fixed, it was fixed in $$anonymous$$ono 3 but Unity is still on 2.2 or something.
I just ran into this problem too. I'm using a generic struct as a handle class.
Best Answer
I hacked around this bug by creating a non generic struct for the SparseGrid that is an int 3 vector, and then writing implicit conversion s to convert to and from the generic the rest of my codebase uses.
But this is really annoying and looks like a compiler bug.
