The following testcase asserts on baseline compiler branch revision b942f88d95c5 (run with --ion-eager):


var buf = serialize(-1);
var nbuf = serialize(undefined);
for (var j = 0 ; j < 1; j++)
  buf[j + 8] = nbuf[j];
Marking s-s since baseline will land soon and this is a security issue. Opt builds crash in various ways where the debug build hits this assertion.

Attached patch PatchSplinter Review
Small fix for StoreTypedArrayElementHole to handle the case where the length is constant but the index is not.
