I think both GCC and CLANG optimize that away. Namely, AECforWebAssembly v1.5.6 (the latest version) parses the Analog Clock example around 10 times faster than AECforWebAssembly v1.5 (before the recent changes).

The initialization may be fast with some compilers, but it cannot be optimized away.

Why?

You are telling the code to do the initialization work when constructing each new instance of the TreeNode class.  The compiler MUST force the program to do that work, because it cannot assume the data has not changed since the last time the work was done.

Okay, but at least you fixed that. It is too bad it didn't speed things up.

Just note - that this is an unsafe construct in a multi-threaded program (but yours isn't, so it is fine). With multi-threading, you have to use some sort of thread lock, not just a single variable.
