Crashing when trying to add a curve to a polyline segment

[chad21mycoopers]

Using Windows 64bit latest version 2024.02. Uninstalled and reinstalled did not fix the crash. Occurred on two different computers.

Create a fresh brand new show directory
Open xLights
Map to the new show directory
Go to Layout tab
Click 3D checkbox
Click Import
Click space to import and select the Tree Top 200.xmodel in the attached zip folder.
Right Click on last segment on the top of the model.
Add Curve

CRASH..
I think it has something to do with the Corners being 'Leading Segment'.
I have modified the Corners to 'Neither' and it seems to resolve the crash.

Not crashing here. (assume you mean 2025.02)
Anything about your configuration?

Can you do a tools->package logs.

Where are you clicking? where is the spot you are adding a curve? I am not that familiar with what you are doing here and am perhaps missing what you are doing.

This crashed..

Can duplicate it .. havent found the answer though..

        while (current_pos > seg_end) {
            sub_segment++;
            seg_start = seg_end;
            segment_length = isCurve ? pPos[segment].curve->GetSegLength(sub_segment) : 1.0f;   // return 0.0 and subsegment goes crazy
            if(segment_length == 0.0f) {
                segment_length = 1.0f;
                break;
            }
            seg_end = seg_start + segment_length;
        }
        glm::vec3 v;
        if (isCurve) {
            v = glm::vec3(*pPos[segment].curve->GetMatrix(sub_segment) * glm::vec4((current_pos - seg_start) / segment_length, 0, 0, 1));
        } else {
            v = glm::vec3(*pPos[segment].matrix * glm::vec4(current_pos / polyLineSizes[segment], 0, 0, 1));
        }
