There is no common C++ ABI. So you get into compatibility concerns
between code built with different compilers (like Studio vs. g++).
Fail.
There are many many things to dislike about C++ -- you *can* write good
clean code in C++, but almost none of the C++ code I've seen fits that
description.
The various side effects, and unexpected memory explosion that occurs
with the "favored" C++ constructs tends to make C++ completely
unsuitable for use in a kernel.
I still have the scars from when Linus tried to experiment with a Linux
kernel in C++. :-) The effort was *very* short lived. Granted C++ has
changed a lot since then, but I think the ways it has changed make it
even more unsuitable for kernel/embedded work.
