Description of problem:
gcc 3.3.2 gives an internal compiler error on the following
preprocessed minimal code while it should just have given a name
conflict error. The error is

test.C:16: internal compiler error: in resume_binding_level, at
cp/decl.c:831
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccwNxp47.out file, please attach
this to your bugreport

The preprocessed code is:    

namespace hi {
        namespace hello {
 
        }
}
 
using hi::hello;
 
namespace hello {
 
}
 
int main ()
{
 
}

--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--host=i386-redhat-linux Thread model: posix gcc version 3.3.2

I think, the problem is that you named the file *.c not *.cpp for 
g++. I had the same problem with cygwin and mingw gcc and wondered,
that there were problems with files named *.cpp.

Try to rename the file to *.cpp and I think, you'll not get that 
problem again.
