My first thought as well.

Then: It is my honest opinion that firmware should not use dynamic allocation of memory at all. It has a well defined job to do; the memory requirements for all tasks should be possible to calculate in advance. That is, the code and data should be structured so that it is possible to calculate all memory needs in advance, and to set off that memory at compile time.

There are reasons why Fortran (with no dynamic memory allocation, and for many versions without a stack - no recursion possible) held up for so long. One of the reasons was that is was reliable wrt. memory allocation: It would never crash due to a failing new() or a too deep recursion.

Ada, made for military robustness, did allow recursion, but only if a static code analysis could calculate the deepest nesting level and stack requirement.

CHILL, created for embedded code in telephone switches, required that you marked functions that are to be called recursively. I don't think it made any difference in generated machine code; it was just a way for the compiler to raise a red flag: Here you make a recursion to a function that is not marked as RECURSIVE. Look out - maybe you will run into stack issues.

Embedded code is executed in an environment where you don't have the same facilities as for desktop applications. Often, less resources are available; you can't just let the stack grow to fill those 16 GBytes of RAM. So, the programmer cannot be allowed the same freedom as a standard application developer. Far more restrictive use of dynamic memory and stack are among the limitations an embedded developer should accept.

I know well that this is certainly always reality in embedded code.
