I haven't looked at this under a debugger, but what I suspect is happening is
this:

In csvText, you're creating a temporary RecordList which is copied on return if
NRVO isn't happening.  The pointer inside recordRange points to the temporary. 
After the copy, the temporary goes away and the pointer is invalid.

Test this by printing the address of RecordList._input inside the RecordList
ctor and again in RecordRange.front.  If I'm right, the two addresses will
differ and the pointer value inside recordRange._input will be the first value.

Assuming all of the above is right, the fix is to add a postblit to fix up the
pointer.
