Steps to reproduce:

1. Just open editor(errors are shown only when compiled Godot with sanitizers support, but It can be easily tracked when putting breakpoint)

I opened an upstream bug report here: memononen/nanosvg#170. It seems like a bug to have an array with exactly one item, what's the point?

typedef struct NSVGgradient {
    float xform[6];
    char spread;
    float fx, fy;
    int nstops;
    NSVGgradientStop stops[1]; // here
} NSVGgradient;

The mentioned issue is still open, so I assume this is still valid.
