You can take a look on how to debug mex files: http://www.mathworks.es/es/help/matlab/troubleshoot-mex-files-1.html

This doesen't seem to be MEX file related to me.

Answer 1

[Andreas Goser]

If it is related to running specific code, I suggest narrowing it down to few lines and provide them (including data that may be needed) to Technical Support.

[Andreas Goser]

PS: I was assuming you already searched for the crash dump on the internet.

Thanks for answering Andreas. The strange part is if I execute my code step by step using the break points, it's always successful. Only when I execute the entire program the crash happens everytime. Do you have any ideas?

[Andreas Goser]

Try disabling the following as first lines of your file. Does it run?

feature('jit',0)
feature('accel',0)

Still, if it works it might be a bug and you should get in touch with MathWorks Support.

Answer 2

Did you get the solution? I encountered the same problem as yours and if I used break point to go through, it worked well

[Andreas Goser]

If it works while debugging, then it usualy means the following line will avoid the crash:

feature('jit',0)
feature('accel',0)

However, it might run slower and please report it to MathWorks.
