Hi Dave et al,

I found a file on which File::LibMagic crashes, please find it here:
https://www.dropbox.com/s/gulodkyzbk12ve4/test.doc?dl=0

% perl -le 'use File::LibMagic;
File::LibMagic->new()->info_from_filename(shift)' test.doc
error calling magic_file: (null) at
/usr/local/lib/x86_64-linux-gnu/perl/5.22.1/File/LibMagic.pm line 107.

openoffice opens the file just fine.

both, File::LibMagic and file(1) link to the same libs, yet file(1)
handles it without a crash.
