 | Known bugs in libpng version 1.4.0beta70 | 
 |  | 
 | 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. | 
 |  | 
 | 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 | 
 |    fails to install symbolic links | 
 |    libpng12.so => libpng12.so.0.1.2.9betaN | 
 |    that are generated by the custom makefiles. | 
 |  | 
 |    STATUS: For now, system library builders should use the custom makefiles. | 
 |  | 
 | 4. November 14, 2006: "make install" fails to build pngdefs.h. | 
 |    "make; make install" works. | 
 |  | 
 |    STATUS:  Under investigation. |
