Description of problem:
When I tried to print out the plain text file, it failed and it seems that gs8
shows an error when PS file from mpage is given.

Version-Release number of selected component (if applicable):
ghostscript-8.15-0.rc3.7 mpage-2.5.4-5

How reproducible:
always

Steps to Reproduce:
1.LANG=ja_JP.UTF-8 mpage -bA4 -l -o -m18lr36bt -P-
/usr/share/printconf/tests/testpage.euc | gs
2.
3.
  
Actual results:
/invalidrestore error appears

Expected results:
no error should happens.

Additional info:
I noticed this problem when I was testing with s-c-p's test printing, but the
printer didn't output anything at all. then tried with lpr, but the dialog said
an error happened or so.  So I've changed LogLevel to debug and see what
happened. it also shows '*** buffer overflow detected ***' message and Backtrace
stuff. although I didn't see this message with mpage | gs on the terminal, will
attach this error_log as well.
BTW a PS file which was generated by mpage on FC5 can be printable on FC4, gs7.
so this is an regression bug, I think.

P.S. Once I stored the output from mpage to the file, and when I give that file
to gs, no error happened. I mean, I did "mpage .... testpage.euc > mpage.ps" and
gs mpage.ps.  However "cat mpage.ps | gs" still shows the error.
