Maybe this is just a time out thing, but we should look into fixing the issue so that the LLINT CLoop bot is more reliable.
This is a regression introduced in http://trac.webkit.org/changeset/169139 which changed VM::watchdog from an embedded field into a std::unique_ptr, but did not update the LLINT to access it as such.
The issue has only manifested so far on the CLoop tests because those are LLINT only. In the non-CLoop cases, the JIT kicks in and does the right thing, thereby hiding the bug in the LLINT.
