Subject: Added missing element in typeof table for DataView() type.
X-Git-Tag: 0.7.1~3
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=d457c9545e7e71ebb5c0479eb16b9d33175855e2;p=njs.git

Added missing element in typeof table for DataView() type.

Previously, typeof operation for DataView object resulted
in out of bounds array accessing.

This fixes #450 issue on Github.
