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

<p>I'm using PD extednded 0.43.4 and have noticed that when using some fonts <span>[text3d]</span> will crash PD when a string with five or more characters is entered.</p>
<p>Font used is Beams: <a href="http://openfontlibrary.org/en/font/beams" rel="nofollow">http://openfontlibrary.org/en/font/beams</a></p>
<p>And the error returned is:</p>
<p><code>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.
