Known bugs and suggested enhancements in libpng-1.0.7
1. March 15, 1998 -- OPTIMIZATION -- Kevin Bracey
1. July 2, 2000 -- BUG -- pnggccrd.c
Some programs compiled with PNG_USE_PNGGCCRD crash in pnggccrd.c.
Also, pnggccrd.c will not compile under gcc-2.95-2.
STATUS: Under investigation. Experts on MMX assembler code are
invited to help with the debugging. Note that pngvcrd.c works fine.
2. July 3, 2000 -- BUG -- MEMORY LEAK
There is a memory leak in pngpread.c; it doesn't free "key".
STATUS: Fixed in libpng-1.0.8beta1, by adding.
png_free(png_ptr, text_ptr);
after lines 1221 and 1038 in pngpread.c
3. July 3, 2000 -- BUG -- PNG_EXPORT_VAR
The definition of PNG_EXPORT_VAR, in pngconf.h, should be
# define PNG_EXPORT_VAR(type) extern PNG_IMPEXP type
STATUS: Fixed in libpng-1.0.8beta1.
4. July 3, 2000 -- BUG -- PNG_NO_STDIO
Several places in pngrutil.c and pngwutil.c, there are printf statements
inside PNG_NO_STDIO blocks (should be PNG_NO_CONSOLE_IO)
STATUS: Fixed in libpng-1.0.8beta1.
5. July 3, 2000 -- ENHANCEMENT -- WindowsCE support
Libpng-1.0.7 does not support WindowsCE.
STATUS: Libpng-1.0.8 and libpng-2.0.0 will support WindowsCE. A
new typedef, png_file_p, will be added which is normally FILE * but
will be HANDLE if libpng is being built for WindowsCE. Other patches
required for WindowsCE support have been provided and will be applied.
