Apparently according to some ACCU and CPPCon talks by Khalil Estel this can be largely mitigated even in embedded lowering the size cost by orders of magnitude.

Need to check it out. I guess you mean these:

- C++ Exceptions Reduce Firmware Code Size, ACCU [1]

- C++ Exceptions for Smaller Firmware, CppCon [2]

Yeah. I unfortunately moved to an APU where code size isn't an issue so I never got the chance to see how well that analysis translated to the work I do.

Provocative talk though, it upends one of the pillars of deeply embedded programming, at least from a size perspective.
