This is not a Ghostscript bug.

The problem is caused by an assumption made by the sample PS program
that findfont always returns a global font when the current allocation
mode is global. This is not the case when TrueType fonts are loaded by
Ghostscript.

The program should be modified as 
/pa_ReEncode {
  pa_reencsmalldict begin    
  /glob currentglobal def  % remember the global flag
  % ...
  /basefontdict basefontname findfont 
  dup gcheck setglobal  % set the matching global mode
  def
  % ...
  glob setglobal % restore the global flag
  end
} def

The user can also upgrade to v. 9.00 and higher.
New versions load TrueType fonts differently, and the font matches the
assumption. However, it is still possible to construct a font
(e.g. Type 3) that will fail the sample PS file.
