You might receive segmentation violation errors or bus errors when you try to access a multilabel format if the format contains a range with more than 4094 labels.

The SAS^® procedures that support multilabel formats are SUMMARY, MEANS, TABULATE, and REPORT. The limit is 255 labels for a single range.

The only workaround is to reduce the number of labels for the range.
