Segmentation fault in `QRCode#pixels`

[gioele]

This simple code will cause a segfault:

require 'qrencoder'
QREncoder.encode('01234567', :version => 1, :mode => :numeric)
p x.pixels

This is the dry message I get:

[BUG] Segmentation fault
ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]

Removing :mode => :numeric solves this segmentation fault but the generated QR code uses another encoding mode.

Please note that the command line qrencode command produces a valid version 1 QR code in numeric mode without segfaulting.

What version of the gem are you using? I believe that we've fixed this issue on master, specifically in dc0f7f0, but have yet to release a new version.

I was using the latest released gem. The example code no longer crashes with the current git code.
