   2 Known bugs in libpng version 1.2.20
   3
   4 1. February 23, 2006: The custom makefiles don't build libpng with -lz.
   5
   6    STATUS: This is a subject of debate. The change will probably be made
   7    as a part of a major overhaul of the makefiles in libpng version 1.3.0.
   8
   9 2. February 24, 2006: The Makefile generated by the "configure" script
  10    fails to install symbolic links
  11    libpng12.so => libpng12.so.0.1.2.9betaN
  12    that are generated by the custom makefiles.
  13
  14 3. September 4, 2007:  There is a report that pngtest crashes on MacOS 10.
  15
  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.
