Many thanks.
If we remove
OBJECT_TYPE_CHECK(objInt);
in getInt(), as in xpdf, the crash disappears.
But this may not be a desirable fix.
See an attached Object.h.diff.

Note that Object.h.r40068 is
texlive/trunk/Build/source/libs/poppler/poppler-src/poppler/Object.h
and it is slightly modified by Peter compared with the
opriginal one in poppler 0.45.0.

Best,
Akira
