[tmodes <2080397@xxxxxxxxxxxxxxxxxx>]

The main cause is that the line cp spans above the 360 deg border. In this case the line is not easily defined.
The cp tab should not draw in this case the line anymore and therefore the assert should be avoided.
Fixed in changeset 01388c79cc55.
If the fix is confirmed I will transplant it to the 2024.0 branch.

** Summary changed:

- Negative content height -2 (allocation 0, extents 1x1) while allocating gadget
+ CP tab: Assert when drawing line cp over 360 deg border

** Changed in: hugin
       Status: New => Fix Committed

** Changed in: hugin
    Milestone: None => 2024.0rc1
