Description:
------------
In PHP 4.3.6 and 4.3.7, with or without zend optimizer, PHP crashes on
ImageCreateFromPNG() if a valid PNG file is specified. Backtrace
follows:
#0 0x00000049 in ?? ()
#1 0x40218dcd in png_create_info_struct (png_ptr=0x49) at png.c:224
#2 0x0809f6d5 in gdImageCreateFromPngCtx (infile=0x84b76b4)

This only happens with libpng 1.2.2 (or 1.2.5), but not with 1.0.13.
