Most likely some change to address a different problem caused this. You can 
use Git to bisect the commits and find what precise commit changed the 
behaviour if you really want to.

However, the problem (or what sounds like it) is not unknown, see :

http://bugs.ghostscript.com/show_bug.cgi?id=696023

and

http://bugs.ghostscript.com/show_bug.cgi?id=695925

If you want someone to look at it specifically, you'll need to open a bug 
report with full details and files required to reproduce the problem.
