I don't think that is the issue - it's not that the output is truncated - it's that there is *no output at all*. Or rather that the link for the "failure" leads to a file which did actually compile correctly.
Is that a symptom of the execution timing out?
Well it says "Compile [2014-02-07 13:37:19 UTC]: succeed" so I took it at it's word ;-) If there is a timeout then it should say so, though there shouldn't be - none of those files take more than a couple of seconds to compile here even on my rather underpowered laptop - if that is the case I would suspect that the tests are run on a virtual machine with little memory available - once you start hitting the swapfile on a virtual machine these builds can take more or less "forever", especially if they're run with a high concurrency value.
