complining error

Dear Admin

I am using the trial version of intel visul fortran 11.01.65 in my research
programming. When I am debugging the program, some time there have been
10 error, some times 7 errors, and at the end "Fatal: There has been an
internal compiler error (C0000005)." without changing the programming
code (debug mode). I want to know why this problem would be occure?
Attached please find the whole of my project?
