[Octave-bug-tracker] [bug #63462] sscanf reports incorrect number of output values.

[anonymous]

Follow-up Comment #19, bug #63462 (project octave):

It seems that the true issue is something else. At several locations in
Octave's code, the stream state is reset and the eof bit is cleared. See
lo-utils.cc:329 for example.

            // True error.
            // Reset stream to original position, clear eof bit, pass status
on.
            is.clear ();
            is.seekg (pos);
            is.setstate (status & ~std::ios_base::eofbit);

So, whenever Octave encounters an eof condition and does not handle it
properly, the same text may be parsed again and again. As a consequence, the
last value in the string may be duplicated if the end of the string is
reached.
