That would depend on who is calling who.  Normally the C/C++ run-time 
arranges to call a main() routine which is not part of libc.  If a 
shared library is involved then shared library initializer functions 
may be called and I am not sure what code is responsible for that. 
If the C++ code has static objects then the C++ run-time needs to 
assure that those are constructed before main() is called.

Regardless, GraphicsMagick has a test in its C++ component (Magick++) 
because this failure to catch exceptions used to be a common problem.
