Heap Failure on deallocation of publisher/subsciber about rclcpp HOT 2 OPEN

I Was thinking in my understanding of rclcpp that a custom allocator would do all the allocating, isn't that the case?

Generally, this should be the case, but I don't believe that we have any test that rigorously guarantees that every piece is using the custom allocators.

Could the fact that the event_handler uses a std::allocator whereas I use a custom one not be a problem?

This is the very likely scenario.

Aren't event_handlers supposed to use the custom allocator?

It should, but once again, there is a chance that it is not.

The best approach would probably be to start looking at the event_handlers and check to see if they are using the custom allocators like they are supposed to. Outside of that, a minimal reproducable example would help a whole lot in investigating this. Getting a Windows + Unreal setup is quite an undertaking.

Could this be related to #2220?

Could the fact that the event_handler uses a std::allocator whereas I use a custom one not be a problem?

This is the very likely scenario.

I think this should not cause an issue as long as each memory location is deallocated using the same allocator that was used for allocating it.
