Dear All,

I'm receiving the segmentation fault during the program debugging in Gfortran built in Code blocks editor. I've deliberately searched to guarantee that I'm not referring to un-allocated array in the code snippets of my program but compiler still complains about the segmentation. I did search the google for that but didn't come up with anything useful. 
I didn't test it fully by if run the "step into" line by line it's seems that at least it reaches the end of program,  I couldn't spot exactly which lines is causing that havoc, I just want to define all of the symptoms in order to make sure the problem is accurately defined. I would like you to take your guidance or anyone who experienced that before and how am I supposed to eliminate it.


Regards,
