Due the jump within the signal trap used in these fuzzers, local scope allocations cannot occur while the signal trap is on, otherwise there is a possibility of leaks. This CL rewrites how the code under test is run, so that the potentially aborting code is tightly wrapped by signal trap without any local scope allocations.
