hi all
Brian Arnold, at Mathworks, often makes informative posts about MATLAB for Mac OSX. This one is about incompatibility between the new Quicktime (7.0.2 or later) and old versions of MATLAB (before R14).

I was wondering if anyone on this newsgroup has experienced the problem I'm currently having with Matlab Student Version, Release 13 on the Macintosh OS X 10.4.2: Since I installed the QuickTime 7.0.2 update using the Software Update application, every time I start Matlab the GUI comes up for about 3 to 6 seconds, then prints a brief message about a segmentation fault and terminates. Every time the program crashes a matlab_crash_dump.xxx file is created in my home directory with contents as follows: (begin file listing) ------------------------------------------------------------------------ Segmentation violation detected at Wed Sep 7 21:45:08 2005 ------------------------------------------------------------------------ | |

Hi,
Here is a defnitive answer, which echoes the definitive answer for
customer bug report 284142, posted on the mathworks web site.
Engineering has identified that the root cause of this problem is with
an OpenGL initialization call which multiple releases of MATLAB R13
make. The defect is in the OpenGL call, whose behavior and requirements
changed in QuickTime 7.0.2 or later.
The code around which this call was made was refactored in R14 SP1 and
later (the call is no longer necessary). Therefore, the problem is not
present in R14 SP1, R14 SP2, R14 SP3, R2006a, R2006b or the R2006b Intel
Mac beta, i.e., any version of MATLAB released in the past three years,
or about-to-be-released.
Apple was made aware of the problem immediately after the problem was
originally reported by our customers, but there is no resolution or
workaround at this time, other than to upgrade your version of MATLAB to
R14 SP1 or later.
I would consider upgrading your version of MATLAB if you intend to use
QuickTime 7.0.2 or later, or otherwise avoid upgrading to QuickTime
7.0.2 or later until Apple has provided a QuickTime update which
resolves the problem.
