handsome_feng <jianfengli@ubuntukylin.com> added in the Debian bug that:

And as such provided this patch:

   fsync (fileno (fileptr));

I'm going to apply that to the Debian package.

Originally reported in Debian: https://bugs.debian.org/970580

Version: 0.0.9-3

At the first start I got

  licensing gpl: got unexpected response code 302 from www.gnu.org/licenses/gpl.txt

I also tested more options and get "Memory access error"

No option gives a result

Another example:

% licensing
licenseutils 0.0.9

To select a license and commenting style use the `choose' command.
e.g. `choose gpl c++'
To see what license a file has use the `detect' command: e.g. `detect *.[ch]'
For a full list of commands type `help'.
// no-license> choose gpl c++
Segmentation fault
// no-license>

Right not I'm a tad unclear on how to get a backtrace from whatever subprocess is spawned.
