<p>When a freeze occurs, it's usually(tm) during an
animation, probably because the movement of an ellipse
is done in small increments of 92 per hop. This is
within a block like so:</p>
<p><br>
</p>
<p>self when: #morphicStep evaluate: [ :delta |
<movement> ].</p>
<p>self startSteppingStepTime: step. <br>
<br>
</p>
How can the breakpoint be set in this block for gdb? We
need source for some C module.<br>

<div>With gdb you can't debug at the Smalltalk level (that's
what alt-. is for). You can only attach to the process,
break into it and figure out what's going on. Which may be
very hard. Also, you may have to compile your own VM with
debug info (or do we have pre-built ones somewhrere?)</div>
