I think it's a problem with some Ghostscript *devices*.

Both PLRM examples render fine with the x11 and png16m devices (and
others), cf. the attached example images generated with:

  gs -dNOPAUSE -dBATCH -sDEVICE=png16m -sOutputFile=test_plrm_ex1.png \
     -r100 -g640x400 test_plrm_ex1.ps

The x11alpha (used by gv) renders example 1 incorrectly and fails with
an "unrecoverable error" for example 2.

The pdfwrite device (used by ps2pdf) renders example 1 incorrectly;
example 2 is rendered correctly.
