Thanks, this helps a lot. So the issue wasn't with "final" being true, and the line the report points to is this one in unit.cpp (607):

delete[] Variable;

The memory in #10 looks different though, so maybe it's two different bug.

in #10:

It seems that #10 is the delete[] Variable line too. (Using the disassembly).

Szunti commented on September 28, 2024

May I ask how was it fixed, or was it?

Andrettin commented on September 28, 2024

Instead of copying variables, I copied their attributes (Enable, Value, etc.) instead, when inheriting from a parent. This should fix the bug, but let me know if it persists and I will reopen the issue.
