Someone commented on my request saying

IIUC it is more of a user-feature right? Like you will use LD_PRELOAD=xxx 
program but not change the environment programmatically in the program? Could 
Emacs do this should tree-sitter doesn’t want to change?

BTW the conversation is at 
https://github.com/tree-sitter/tree-sitter/issues/1535

The author suggested to implement runtime change of malloc on top of current 
macros, but I think he missed the point (we don’t want to maintain our own 
version of tree-sitter).
