10.2.1 Program Sections problem

Has anyone run into a problem with 10.2.1 programs using "sections". I can compile on version 10.0.1 and the program works fine. I compile the same program with 10.2.1 and it "Falls Thru"  past the next section and crashs. I took out all "sections" and changed to xxxx thru xxxx-exit.  exit and it works fine..
