This is a quick hack to avoid the ICEs reported for many
	C++ applications.  It trivially avoids the ICE by skipping
	the sweep of string variables that sweep_string_variable
	doesn't understand.  If those variables _should_ have been
	swept, then overflows on these variables may corrupt other
	scalar data; however if this works it's better than switching
	off SSP completely.
