I am unable to reproduce the crash the bots saw, but it appear stop be in the TestRunner InjectedBundle overflowing a Vector bounds:

    Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
    Exception Codes: KERN_INVALID_ADDRESS at 0x00000000bbadbeef

    ...

Perhaps this is flakey on the bots or related to other tests running simultaneously.
