The following testcase asserts on mozilla-central revision 18467a85acf6 (run with --fuzzing-safe --ion-eager):
var buf = serialize(new Date(NaN));
var n = -(8.64e15 + 1);
var nbuf = serialize(n);
for (var j = 0; j < 8; j++)
buf[j + (0.00000000123)] = nbuf[j];

This is slightly different from bug 893732 (affects stores rather than loads) but will be fixed by that bug.
