**Describe the bug:** When compiling ``master`` with GCC 14.1.1, I am getting the following error message: ``` [...]/BehaviorTree.CPP/include/behaviortree_cpp/flatbuffers/stl_emulation.h:549:12: error: assignment of read-only member ‘flatbuffers::span<T, Extent>::count_’ 549 | count_ = other.count_; | ~~~~~~~^~~~~~~~~~~~ ``` This was fixed in flatbuffers with https://github.com/google/flatbuffers/pull/7227. It seems that the new GCC version somehow detects this error now as well. This also affects the v3.8 branch. **How to Reproduce:** Compile BehaviorTree.CPP with GCC 14.1.1
