Except for the problem, that I do not have CompTrap and CompSimp, your code runs as expected on my computer.

The message "Program terminated." is confusing. It looks strange, that the code contains the part for the integration twice. But at least nothing stops.

I suggest to use the debugger to step through your code line by line. Then it should be easy to find out, what's going on.
