MEX, gcc, segmentation violation

Hi,

I'm currently using a mex function which crashes at a certain point (Segmentation Violation).

how can I debug it? (I'm using Linux Mint)

moreover, when I try to compile the mex fuction, I get the following warning:

Warning: You are using gcc version '4.8.2'. The version of gcc is not supported. The version currently supported with MEX is '4.7.x'.

Might this be the cause? Should I revert back to g++ 4.7.x? How? Won't an older compiler affect the stability of my OS?

Stefano - can you post the code that is causing the crash, or at least the portion of it that is generating the segmentation violation? The message that you are seeing is "just" a warning so may not have anything to do with the problem you are experiencing.
