Sorry for that question, but: were you able to reproduce the issue at 
all, i.e. with the unpatched libpng?
As Aaron wrote in his initial post he was unable to create a minimal 
example, meanwhile it was quite easy as described by Akira. For me that 
minimal example worked, but I suspect this is not the case everywhere.
