example.pdf

OS: Fedora 20 (running in virtualbox)
Dependencies installed with: yum-builddep poppler
Version: GIT Master
Command line for loop demonstration: master/utils/pdftohtml <attached.pdf>
/dev/null

Note, repeats with all PDFs I tried (i.e. also not fuzzed ones). Tried also by
making with root folder /new and writing there. Both GDB information attached.
Also possible to repeat with:

mkdir out
chmod 000 out
master/utils/pdftohtml <any.pdf> out/out
