Ok, I have no idea what's going on there (and this isn't the place to
track it down).  I also have no idea what's "rather advanced" about your
C++ code (no, I'm not asking).

Your C++ compiler sometimes crashes and you don't know why.  Is that
really the only basis for your assertion that it must have started out
as an Objective-C compiler?  Seriously?

No, there is no philosophical question.  gcc is a compiler system
produced by the GNU project.  clang is a different compiler system
produced by a different group, using LLVM as its back end.  They are
largely compatible, but very clearly not the same thing.  Apparently
there's also some interoperability between their respective front
end and back ends.  For convenience, Mac OSX uses a command with
the name "gcc" to invoke the clang compiler, probably because a
lot of Makefiles assume that the C compiler command is spelled "gcc".
