And it gets activated when building on a 64-bit system only. Could you 
please take a look at the make/sun/splashscreen/Makefile file and make 
sure it defines the "CPPFLAGS += -DPNG_NO_MMX_CODE" in every case. It is 
really very interesting if this will resolve the issue. Thank you in 

This is not an ideal solution. Updating to a new libpng version would be 
fine, however these should be some clean sources (i.e. vanilla libpng 
source tarball, w/o any static <-> const swaps, etc.), and secondly it 
requires some Sun-internal bureaucratic process to put these sources to 
the OpenJDK source tree.

Currently I don't see the suggested change is justified since using the 
standard build environment does not reproduce the problem. However, you 
might probably be interested in fixing the following CR: 
This would eliminate this problem at once and forever. Diego 'Flameeyes' 
Pettenò didn't provide us with a working patch (please see the archives 
of the awt-dev mailing list), hence the CR has been suspended.

best regards,
