issue with "axoverlay_set_overlay_size" fw 10.8.1 +

[paromarc]

Describe the bug

Hi,

I have been testing the Cairo overlay APIs in ACAP3 and 4 and came across an issue when using axoverlay_set_overlay_size causing a crash.

I am testing on a Q1615 MKIII and the issue started from fw 10.8.1 (before that release all was working fine) and higher. I managed to narrow it down to this specific function: "axoverlay_set_overlay_size" which allows to resize a box. I have also created a couple of videos showing what happens.

Here is a demo video showing the test application not using the "axoverlay_set_overlay_size" -->

And here is the test application using "axoverlay_set_overlay_size" -->
https://www.youtube.com/watch?v=6KoEoPeFKe8

When running the same sample test code on fw 10.7.3 I have no issues.

To reproduce

Use "axoverlay_set_overlay_size"

Steps to reproduce the behavior:

Run the "axoverlay_set_overlay_size" on fw 10.8.1 and higher through ssh terminal. Logs will show this message:

overlaytest: src/overlay.c:749: overlay_free_overlay_context: Assertion `ovl_table != NULL' failed.
