A: This is a bug in the current release, and will be fixed in the next release. The procedure tried to create a table with over 1000 rows (the independent variable has over 1000 unique values). In the process, the system tries to create a 2000x2000 matrix. The crash results as a function of a page fault or exhausted virtual memory, and can occur whether or not you try to cancel the run. Prior to the next release, try to avoid tables with so many rows.
