So running out of memory. 4.5 Gb does sound excessive.

Well, I kept an eye on a normal build and ... it does seem to use Gigabytes of memory. Did the VM have less memory than autobuilders typically do?

That might have been a meaningless question: piglit probably isn't part of any autobuilder images (unless there's a world build).

According to the blocked bug # 11608 this is during a nightly-world: 

"Ubuntu17.04 past all test-matrix except nightly-world, you said that this issue is because the host is running out of memory and OOMing the webkit build, but the host has 32Gb of RAM."
Comment 5 Jussi Kukkonen 2017-06-13 19:33:53 UTC 
Closing as not a bug: the test machine had less swap than the current autobuilder instances and run out of memory. Both piglit and especially webkit have very high peak memory usage: 32 GB may not be enough for a world build if large values of PARALLEL_MAKE are used.
