ZScript compiler crashes out with complex dynarray access

[ZZYZX]

I started writing yet another weird project and it broke in the most unexpected place.
This function crashes compiler while initializing ZScript files (attempt to read from 0000000000000068):

Code: Select all

    void SetFrame(int index)
    {
        for (int i = 0; i < triangles.Size(); i++)
        {
            triangles[i].v1 = frames[index].vertices[triangles[i].iv1];
            triangles[i].v2 = frames[index].vertices[triangles[i].iv2];
            triangles[i].v3 = frames[index].vertices[triangles[i].iv3];
        }
    }

(it's in zscript.txt, in the attached pk3)
If changed to this:

Code: Select all

    void SetFrame(int index)
    {
        C3DFrame frame = frames[index];
        for (int i = 0; i < triangles.Size(); i++)
        {
            C3DTriangle triangle = triangles[i];
            triangle.v1 = frame.vertices[triangle.iv1];
            triangle.v2 = frame.vertices[triangle.iv2];
            triangle.v3 = frame.vertices[triangle.iv3];
        }
    }

It compiles and functions as expected.

It's a known limitation at the moment. It was already reported at least once here.

So does this commit fix the issue?

No, it’s for different issue.
