Do people sometimes use 3rd party memory allocators when developing C code on (say) STM32 boards?

In C we have lib functions malloc and free and the basic implementations we use can be replaced with others but how often is that done and what problems are people addressing when they do this?

 

I am going to guess most of us do not use dynamic memory allocation on micros. I don’t.

 

I've never had a need to use dynamic memory allocation on an embedded system. It has always been bare metal development.
