I guess I still question why you are not just calling yy_scan_bytes. If
you look at the output of flex it contains the source code for
yy_scan_bytes, which shows it doing *exactly* the same thing (allocating
a buffer 2 bytes larger, copying the memory block, setting the nulls,
then calling yy_scan_buffer, and sets things up so resetting the scanner
deletes the temporary buffer).
It just seems to me that this code serves no purpose, and that if flex
is ever "fixed" to not require the bytes (most likely by making it reuse
the code to read blocks from files to read blocks from the source
buffer), that this patch would then not use this fix and have to be
removed anyway...
