The problem is reproduced on Mac OS and Linux 64bit.
My compilation environment was a little different from the standard one.
I had search path:
   %rom%Resource/Init/ : %rom%lib/ :
   /home/alexcher/gs_svn/gs/Resource/Init :
but default build has
   . : %rom%Resource/Init/ : %rom%lib/ :
   /usr/local/share/ghostscript/8.72/Resource/Init :
   /usr/local/share/ghostscript/8.72/lib :
   /usr/local/share/ghostscript/8.72/Resource/Font :
   /usr/local/share/ghostscript/fonts :
   /usr/local/share/fonts/default/ghostscript :
   /usr/local/share/fonts/default/Type1 :
   /usr/local/share/fonts/default/TrueType : /usr/lib/DPS/outline/base :
   /usr/openwin/lib/X11/fonts/Type1 : /usr/openwin/lib/X11/fonts/TrueType :

I can avoid the crash by adding more search paths with -I option.
Before the crash -Z? reports "Bad object ...". The offending object is
gx_path structure.
