Well here is what happens with reduced.pdf . It paints an imagemask with a 
pattern 1 color, which contains a Type 1 image, which represents the graphics 
that we can view with Acrobat.

Ghostscript converts the pattern into a clist based representation. When it 
does, the CTM for the image appears to have a huge offset ty=2359296.0 . I 
don't know yet why so happens, but it causes some overflows, so that the image 
rect appears empty. The latter is wrong. Then it creates an empty clist, and 
then playing it back later, Ghostscript paints nothing.

So I'd like to know why 'ty' is so big and why it causes an overflow (IMO it's 
not so big to overflow 'fixed').
