| Known bugs in libpng version 1.2.19rc1 |
| |
| 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. |
| |
| 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. |
