The error is some general sort of memory corruption, but without the data or parameters to reproduce it I can't really say more. Since this is an STSDAS calibration task your best bet may be the ST helpdesk (email@example.com). They would probably want to know which IRAF and STSDAS version you are using.
Note I'm assuming you're using a version that has the Jan14 critical update installed and that your STSDAS was linked against that. This fixed something that could explain your problem, especially because of your use of image sections.
