This is compiler specific and cannot be generalised as C++.

[zabzonk]

Well, yes, but still quite interesting, IMHO. It's not like GCC is one of the least used compilers.

[pjmlp]

Yeah, but that isn't C++ in isolation, thus the tile is incorrect.

[compiler-guy]

And C++ library specific as well. Perhaps even more so.

I would also expect it to depend on whether or not you have exceptions enabled. Half the ecosystem has them disabled.
