/bin/page hangs

[jibanes]

/bin/page hangs on this simple file (within the zip attached).
file.zip

It doesn't hang, but simply fails for me:

$ gs --version

$ unzip file.zip

$ page -v vp90251.ps

However, I can successfully produce the BMP file with this ghostscript command:

$ gs \
      -dNOPAUSE \
      -dNOPROMPT \
      -dDELAYSAFER \
      -dQUIET \

      -dGraphicsAlphaBits=4 \
      -o output.bmp \

I was getting the invalidfileaccess error because I was passing a relative path to the ps file. It displays the ps file and hangs as originally reported if I pass an absolute path:
page $(pwd)/vp90251.ps instead of page vp90251.ps. This is due to to the run operator not liking a relative path (security risk?). See https://www.ghostscript.com/doc/current/Use.htm#Finding_files
