Although the segmentation error continues, I no longer have the problem.

In the line that looked a little like the (corrected below) line, there
were no parens, but parens  were needed. So I suspect that the uncorrected
line produced the setting for the segmentation error as it also included
the {{ but they were treated as if the _3 went with the first {.

($w)(,;._3 ){{i."0$i
