1. April 22, 2001: pnggccrd.c has been reported to crash on NetBSD when
2002-07-08 00:15:20 +00:00
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
2002-06-20 11:54:34 +00:00
fixed a problem under FreeBSD but not the problem with NetBSD, which
still fails as of libpng-1.2.2rc1.

2. February 23, 2006: The custom makefiles don't build libpng with -lz.
STATUS: This is a subject of debate. The change will probably be made
as a part of a major overhaul of the makefiles in libpng version 1.3.0.

3. February 24, 2006: The Makefile generated by the "configure" script
2006-03-02 13:23:18 +00:00
fails to install symbolic links
libpng12.so => libpng12.so.0.1.2.9betaN
that are generated by the custom makefiles.

4. June 28, 2007: Pnggccrd.c has been reported to be unreliable on
several 64-bit platforms running gcc-3.x. Although it appears to
build properly, it does not always read files correctly.
STATUS: Appears to be a bug in the 64-bit version of gcc-3.4.6.
Workarounds are to define PNG_NO_MMX_FILTER_UP|AVG|PAETH (as in
pngconf.h) or to upgrade gcc to a newer version.
