-Known bugs in libpng version 1.2.5rc3
+Known bugs in libpng version 1.2.34
-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.
+1. February 23, 2006: The custom makefiles don't build libpng with -lz.
- 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.
+ 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 1.4.0.
+
+2. 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.
+
+3. September 4, 2007: There is a report that pngtest crashes on MacOS 10.
+
+ STATUS: workarounds are
+ 1) Compile without optimization (crashes are observed with
+ -arch i386 and -O2 or -O3, using gcc-4.0.1).
+ 2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
+ you try to look at it).
+ 3) Ignore the crash. The library itself seems to be OK.
