thanks for figuring out the problem.
anyhow: my opinion is that Gem is not at fault here.
Gem uses [FTGL](http://ftgl.sf.net) for font rendering (FTGL in turn uses
libfreetype to decide the font), and it seems that it is really FTGL that is
crashing.
doing a quick check with FTGLDemo (2.1.3~rc5) shows that FTGL is indeed
crashing:
- start `./FTGLDemo /path/to/Beams.ttf`
- (rendering seems to work though there are a lot of artefacts)
- type <kbd>Left</kbd> (*ARROW-LEFT* to decrease font-size)
- CRASH
alternatively running `./FTGLMFontDemo /path/to/Beams.ttf` immediately crashes.
the problem persists with the current SVN version of FTGL.

** [bugs:#220] [text3d] crashes PD if the letter "p" is typed**

I'm using PD extednded 0.43.4 and have noticed that when using some fonts
[text3d] will crash PD when a string with five or more characters is entered.
Font used is Beams: http://openfontlibrary.org/en/font/beams
And the error returned is:
``pd: ../src/libtess/priorityq.c:164: __gl_pqSortInit: Assertion `((((GLUvertex
*)**(i+1))->s < ((GLUvertex *)**i)->s) || (((GLUvertex *)**(i+1))->s ==
((GLUvertex *)**i)->s && ((GLUvertex *)**(i+1))->t <= ((GLUvertex *)**i)->t))'
failed.
Pd: signal 6``
I using a Dell XPS 13 developer edition running Ubuntu 13.10 with Intel®
Ivybridge Mobile graphics and Intel® Core™ i7-3537U CPU @ 2.00GHz × 4 processors
I've attached a patch and the font file for testing
