It depends on if you are trying to minimize a testcase for C++ FE bugs, 
or an optimization bug.
For the case of C++ FE bugs, yer right, you will need to integrate it 
with some C++ syntax aware minimizer.
For the case of optimization bugs, you are looking at the problem the 
wrong way.
See LLVM's bugpoint for a tool that does this right.
