"Assertion Failed" error

Program: C:\gs\gs8.14\bin\gswin32c.exe
File: .\src\gxccman.c
Line: 576
Expression: cc->pair==pair

I get this error when attempting to process this file:
http://www.pacificpremedia.com/gs/DR.zip
(ZIPed Illustrator EPS file)

The error only occurs with certain options. This command will cause the error:

gswin32c.exe -q -sDEVICE=psdcmyk -dTextAlphaBits=4 -r150x150 -
sOutputFile=C:\gs_output.psd "C:\DR.eps"

while these commands will process just fine:

gswin32c.exe -q -sDEVICE=psdcmyk -dTextAlphaBits=4 -
sOutputFile=C:\gs_output.psd "C:\DR.eps"

gswin32c.exe -q -sDEVICE=psdcmyk -r150x150 -
sOutputFile=C:\gs_output.psd "C:\DR.eps"


So it appears that a combination of "-dTextAlphaBits" and "-r" is the root of 
the problem. Most EPS files process with no problems. This particular one uses 
a non-standard font, which may or may not be contributing to the problem:

%%DocumentFonts: HiraKakuPro-W3-83pv-RKSJ-H
%%DocumentNeededFonts: HiraKakuPro-W3-83pv-RKSJ-H

It looks like this error has been bugged before and that it was fixed. I tried 
8.15 and got he same results however.
