I have worked on a few C++ projects in my time, all of which have ended in tears one way or the other. At the most fundamental level, the truth is that people can't be trusted. They can't be trusted to write good code, they can't be trusted to debug it, and they certainly can't be trusted to understand it when they have to come back and modify it again weeks/months later.
C code doesn't have a lot of the weird stuff in C++ that makes it hard to debug (constructors/destructors, anything that happens with static global objects during cpp_initialize() time, etc.). That just makes it easier to deal with when developing and maintaining a big project.
Maybe I'm a luddite, but every time someone says "C++" around me I get shivers.
