Likely caused by extended checking. Works with x86_64.

[Yufeng-a (yufeng-a)]

The failure seems a bit random; it is fine in my local environment with r210436 (trunk 20140514), but after I applied a patch in order to do the bootstrapping test on aarch64, I got the exactly same error.

[Doko-v (doko-v)]

builds again on the trunk
