My description above was empirical.  I determined it by actual testing
of the PDFs the OP referenced.  I have:

http://ardownload.adobe.com/pub/adobe/reader/unix/8.x/8.1.2/AdobeReader_enu-8.1.2-1.i486.tar.bz2

installed (by way of the Gentoo ebuild).

Albert> Show such a document to me, that's been working for ages.

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
annotation.

(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:

(gdb) where
#0  0xb7de7303 in AnnotWidget::initialize () from /usr/lib/libpoppler.so.3
#1  0xb7de9c4d in AnnotWidget::AnnotWidget () from /usr/lib/libpoppler.so.3
#2  0xb7deb6b1 in Annots::createAnnot () from /usr/lib/libpoppler.so.3
#3  0xb7deba00 in Annots::Annots () from /usr/lib/libpoppler.so.3
#4  0xb7e51496 in Page::displaySlice () from /usr/lib/libpoppler.so.3
#5  0xb7e54cc7 in PDFDoc::displayPageSlice () 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....
