We've tested ImageMagick 6.2.9 on HP-UX 10.20, 11.00, 11.11,
11.23/PA-RISC, and 11.23/IA-64. Works fine on 11.23/IA-64 but .ps
files seem to be generated incorrectly on any version of
HP-UX/PA-RISC. Odd that this is limited to PA-RISC.
I created a wrapper around the `gs' binary to pause at every
invocation so I can inspect the input files being sent to it.
$ cd /opt/build/ImageMagick-6.2.9
$ PATH=/tmp:$PATH gmake TESTS=tests/rwblob_EPT_bilevel.sh check

I've attached a copy of /var/tmp/magick-b0002013 and
/var/tmp/magick-d0002013. The file corruption occurs in
/var/tmp/magick-b0002013.
I've tried building with both the HP-UX C compiler and GCC 3.4.3. Both
exhibit the same result. Any clues on where I can start debugging?
