Exceptions are still a no-no for code that needs to be real time due to it's non-deterministic nature. The feature can be disabled with the -fno-exceptions flag. However, this might change in C++23. Herb Sutter just proposed C++ switch to deterministic exceptions. The paper is quite good: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0709r0.pdf http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p070... It looks popular, so there is a high chance it will become a thing allowing stl to work in the embedded world.
