is this actually a bug?

gcc-3.4 (CVS 20040113) and 3.5 (CVS 20040113 tree-ssa) are more verbose:

$ /usr/lib/gcc-snapshot/bin/g++ bug-228099.cc && LD_LIBRARY_PATH=/usr/lib/gcc-snapshot/lib ./a.out 
terminate called after throwing an instance of 'i'
Aborted

$ /usr/lib/gcc-experimental/bin/g++ bug-228099.cc && LD_LIBRARY_PATH=/usr/lib/gcc-experimental/lib ./a.out 
terminate called without an active exception
Aborted
