Known bugs in libpng version 1.2.18

1. April 22, 2001: pnggccrd.c has been reported to crash on NetBSD when
5
reading interlaced PNG files, when assembler code is enabled but running
6
on a non-MMX i386 platform.
8
STATUS: Under investigation. The change to pnggccrd.c in libpng-1.2.1
9
fixed a problem under FreeBSD but not the problem with NetBSD, which
10
still fails as of libpng-1.2.2rc1.
12
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
15

as a part of a major overhaul of the makefiles in libpng version 1.3.0.

that are generated by the custom makefiles.

STATUS: For now, system library builders should use the custom makefiles.

4. March 2007: Building 1.2.16 with PNG_ASSEMBLER_CODE_SUPPORTED;
25
PNG_MMX_CODE_SUPPORTED results in multiple definitions of png_combine_row,
26
png_do_read_interlace, and png_read_filter_row
28
STATUS: Investigating.

3. September 4, 2007: There is a report that pngtest crashes on MacOS 10.
16
STATUS: workarounds are
17
1) Compile without optimization (crashes are observed with
18
-arch i386 and -O2 or -O3, using gcc-4.0.1.
19
2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
20
you try to look at it).
21
3) Ignore the crash. The library itself seems to be OK.
