Bug 701785: fixed sanitizer heap-buffer-overflow in lprn_is_black().
In contrib/lips4/gdevlprn.c:lprn_is_black(), it seems that bpl is not
necessarily a multiple of lprn->nBw, so we need to explicitly avoid straying
into the next line's data.
This also avoids accessing beyond our buffer if we are already on the last
line, and so fixes the sanitizer error.
Fixes:
