The problem is caused by FontDirectory pointing to a global
directory in local mode. The mismatch between currentglobal
and FontDirectory state seems to happen after unsuccessful
attemt to find an Asian font.

/definefont
 { 
   % .....
   dup .FontDirectory 4 -2 roll .growput  % <- it fails in
growput
   % .....
 } odef

The bug is caused by non-standard /SubstituteFont procedure.
The standard procedure takes a name and returns another
name. GS takes many arguments and returns a font. This fix
brings GS up to the standard while retaining some backward
compatibility.

The sample file replaces SubstituteFont with {pop /Courier} .
This caused stack mix-up, triggered error recovery and
caused other problems later on.
