Bug#691715: [rt.cpan.org #80458] libtext-bibtex-perl: syntactically invalid BibTeX file crashes perl

Using bibparse is nice, it eliminates some complications.

OK, here is my current test, on the bib file above.

install debian compile 0.66 into /usr

Install 0.66 from source into /usr/local.

run bibparse, no crash.

mv /usr/local/lib/libbtparse.so out of the way, so 

ldd /usr/local/bin/bibparse reports 

libbtparse.so => /usr/lib/libbtparse.so

i.e. linked to the debian version.

Now bibparse crashes on that file again with a buffer overflow, after
printing
