Please follow these steps to report this problem to The MathWorks so we
have the best chance of correcting it:
 
The next time MATLAB is launched under typical usage, a dialog box will
open to help you send the error log to The MathWorks. Alternatively, you
can send an e-mail to segv@mathworks.com with the following file attached:
    /home/frejus/matlab_crash_dump.8378
 
If the problem is reproducible, please submit a Service Request via:
    http://www.mathworks.com/support/contact_us/ts/help_request_1.html
 
A technical support engineer might contact you with further information.
 
Thank you for your help. MATLAB may attempt to recover, but even if recovery appears successful,
we recommend that you save your workspace and restart MATLAB as soon as possible.
