Segmentation Fault When Resetting Animation Overrides

[theashraf]

I am encountering a segmentation fault error in dotlottie-rs when trying to reset the applied slots overrides object for this Lottie animation: favorites_active.json.

The applied slots overrides are as follows:

{
    "lottie-icon-outline": {
        "p": {
            "a": 0,
            "k": [1, 1, 0]
        }
    },
    "lottie-icon-solid": {
        "p": {
            "a": 0,
            "k": [0, 0, 1]
        }
    }
}

Please note that the lottie-icon-solid property is animated color in the provided animation with keyframes. Changing it to non-animated in the overrides could be causing the issue 👀 ?

Thanks, @theashraf. We will have a look on this as soon as possible.

Hello @theashraf.
I tested Slot override & reset. In ThorVG on my machine, I did not encounter segmentation fault error.

I don't find any relevance to segmentation fault from dotlottie-rs.

We also noticed a bug in Slot resetting in this file. After resetting the slot, the styles do not render to their original color(blue), it's rendering a black star, which is not the original look.

Perhaps, some sort of bugs affecting the color could cause segmentation fault in dotlottie-rs, not sure yet. I'll keep track on the resetting bug.

@tinyjin did you check with sanitizer?

@hermet Ooops.
I've got a heap UAF with sanitizer. I'll take care of it. This might be potential crash in Rust system.
