Maybe so.

The things that seem to get more often broken (in my experience) are 
things like the different rules about pointer conversions and the fact 
that prototypes are required in C++.  (The latter is something that we 
should already be catching with warnings in GCC.)  The conversions 
between enumerations constants and integers (or lack thereof in C++) is 
another place where people can easily write valid C that isn't valid C++.
