Please post the relevant code, including data definitions. Can't say otherwise.
SSRANGE should not prevent an abend, it should abend itself if you access storage outside a Cobol table (occurs) with a subscript, index or reference-modification. It will provide information about the problem as well.
This would indicate that you still haven't recreated the situation in your test environment. Or, just possibly, you have managed to overwrite some code, and the inclusion of the SSRANGE code has made that overwriting in a less "vital" place or value. This is, however, unlikely. Don't bother looking into that until all more reasonable possibilities exhausted.
To try to recreate the problem, you need your compile options all the same as production.
