Original Poster.

I went to page 6 of 18 (which is labeled page 18).  Near the bottom,
the last line of the penultimate paragraph is « Figure 1. »  If I hover
over the « 1. » a note pops up to click to see that figure, mentioning
that it occurs on page 19.  After clicking an annot pops up (I presume
due to some ecma-script).  Hoverring over that annot brings up the help
info to shift-click to move it around.  A shift-click (not a click-drag,
just a click) makes the annot follow the pointer.  At that point a left
click anchors it.

Ah.  It only works for the popup annot, which you only get on the
reference to the figure, not on the figure itself.

The idea (of the TeXnicians who came up with it) was to make it possible
to see the figure even if it is not on the same page, w/o having to
navigate around the document.

Makes sense.

>> annotation.

Albert> Not true, i have lots of PDF with annotations that work.

By "those PDFs" I meant specifically the two that Ross posted about, not
all PDFs with links in general.  I hadn't noticed the ambiguity until
just now.  Appologies for that!

After I recompiled poppler and xpdf-on-poppler with -ggdb I no longer
get the SEGV from pdftoppm, only from xpdf.  It looks like:
