[pdftex] pdftex core dump when including certain pdf files

[KAKUTO, Akira]

Hi Norbert,

> But this may not be a desirable fix.

If we use getNum() instead of getInt() in pdftoepdf.cc,
tryplot.pdf is created successfully even if we use poppler.
But I don't know the change is harmless or not.
See an attached pdftoepdf.cc.diff.

Best,
Akira
