Summary: pdf device segfaults on example 24

Initial Comment:
On Debian stable, with libharu-2.1.0 built from source, example 24 generates a segfault like this:

examples/c/x24c -dev pdf -o test.pdf
ERROR: error_no=1050, detail_no=0
Segmentation fault

Here is the corresponding valgrind messages:

Segmentation fault

So it appears there is some issue with the HPDF_Free call for the 24th example that does not appear for any other example.  (Note that if I adjust test_c.sh to drop example 24 "make test_c_pdf" completes without any obvious errors.)
