Yes more, but the picture is still not crystal clear. 

Does setvbuf() work under any circumstances on your OS?  If it simply never works, then

    be sure and make it conditional in *both* FILE_LINE_READER constructors.

    consider filing a bug report with your OS (glibc) maintainers.


The newer FILE_LINE_READER::FILE_LINE_READER( const wxString& ) will be getting more and
more use with time.
