When processing the SAS system option OPLIST in the UNIX environment, a single-byte memory error occurs, causing a segmentation violation error if that byte happens to reside on a unallocated page.

The segmentation violation error occurs only under very specific circumstances. One customer running SAS on Solaris reported that only a sas command line-length of exactly 491 characters would elicit the error. It is possible, however, that other factors could combine to cause the segmentation violation error in other circumstances.

The segmentation violation can be averted by not specifying the OPLIST SAS system option.
