As Lowell suggested in another email, you could test to see if the 
problem happens with the mapserv CGI.  If the problem can't be 
reproduced with the CGI, then the next place to look would be making 
sure that if your PHP has the GD module enabled then it uses the exact 
same copy of GD as php_mapscript. This is a common problem that happens 
if PHP uses its builtin GD (the default), or if you have multiple copies 
of GD on your system.

Another possible source for this problem is that GDAL comes with its own 
builtin copy of libpng, so you may have to make sure that it uses the 
system copy of libpng.

The fact that you use libpng from www.sunfreeware.com or any other place 
shouldn't matter as long as all the components that you link together 
use the exact same copy of libpng.
