It works by calling abort(), as intended.

If you take another look in functexcept.cc you'll see that when
__EXCEPTIONS is defined the following definition is used:

  void
  __throw_logic_error(const char* __s)
  { throw logic_error(_(__s)); }

This allows the library to call __throw_logic_error without caring
whether the target supports exceptions, or whether they have been
disabled with -fno-exceptions.  If exceptions are enabled
__throw_logic_error will throw std::logic_error, otherwise it will
call abort().

It seems that the 68k amigaos port does not support exceptions, or
your GCC was configured without support for exceptions.

Hope that helps,
