Your problem appears to be that you have a file named 'exception' which is an 
ELF executable, in your compiler's include path.  It seems to be in the 
directory of the test, which is weird.  But the result is that the compiler 
uses this file when it compiles "#include <exception>", instead of the "real" 
'exception' file coming from your standard C++ library.

So find that file, and move it elsewhere.

Cheers!
