Known bugs in libpng version 1.2.8 1. April 22, 2001: pnggccrd.c has been reported to crash on NetBSD when reading interlaced PNG files, when assembler code is enabled but running on a non-MMX i386 platform. STATUS: Under investigation. The change to pnggccrd.c in libpng-1.2.1 fixed a problem under FreeBSD but not the problem with NetBSD, which still fails as of libpng-1.2.2rc1.
