A posting at http://cmpg.unibe.ch/software/BayeScan/download.html 
suggests that such assertions can be due to an OpenMP bug in the 
compiler used.  I see other postings which suggest that "Abort trap: 
6" can occur due to other issues as well.

OS X in general is problematic with GraphicsMagick due to OS X 
switching its compiler GCC to clang and clang not quite supporting 
OpenMP yet.  I have also heard of issues when POSIX threads are used 
with OpenMP on OS X.

Since the problem occured only in the drawing tests, it is possible 
that GraphicsMagick has a bug related to drawing.

What is the full output of

   ./utilities/gm -version

in the build directory where this problem is occuring?

You don't seem to have any add-on libraries available at all, which 
means you might be testing cases that I don't usually test here.  Your 
GraphicsMagick would be very bare-bones without even JPEG or PNG 
support.

I don't have a modern Mac OS X system here to test with, but if 
someone is willing to contribute one, it would be appreciated.

The drawing tests do pass 'valgrind' checks on a Linux system.
