The type std::logic_error isn't supposed to print anything, it just
holds a string.

In current versions of GCC the default terminate handler (called when
an exception is not caught) will print out the message, see
__verbose_terminate_handler() in libsupc++/vterminate.cc

Any printing is done by code that handles the exception, not by the
exception itself.
