My description above was empirical. I determined it by actual testing
of the PDFs the OP referenced. I have:
installed (by way of the Gentoo ebuild).

Again, xpdf compiled against libpoppler (Gentoo’s way of installing
xpdf; I use git master libpoppler) does die on any page of the OP’s
referenced PDFs where there is any annotation. I listed the only
types of annotations in those documents. The full backtrace is:

I didn’t post it initially because it lacks arguments. I had presumed
that it would be easy to duplicate.
That exact bt occurs on any page of those PDFs which has any kind of
(And I have recompiled xpdf after my most recent recompile of poppler.)
If I run a compile of xpdf302 as distributed by upstream — which of
course does not have any annot support — there is no crash.
For pdftoppm the bt is:
#0 0xb7de7303 in AnnotWidget::initialize () from /usr/lib/libpoppler.so.3
#1 0xb7de9c4d in AnnotWidget::AnnotWidget () from /usr/lib/libpoppler.so.3

#6 0x08049143 in savePageSlice ()
#7 0x0804979d in main ()
and also happens on pages with annots.
The OP get’s a bus error on OSX; I a SEGV on Linux.
To help debug this I will recompiled poppler and xpdf with -ggdb and
post better backtraces. And core files if you like. It might take
a bit, though. I’m currently compiling axiom, and axiom’s readme
predicts a multiple-hour compile time on a much better box than mine....
