Further investigation reveals that getn uses a similar conversion and
can crash in the same way.

(While I was looking at getn I noticed)
There is a bug in the documentation for getn.  The documentation says:

... the largest numerical index with a non-nil value in the table

but the following code prints 0:

print(getn{[-9]="foo"})

So the documentation should say:

This number is the value of the table field n, if it has a numeric
value, or the largest positive numerical index with a non-nil value
in the table, or 0 if no such index exists.
