It broke half of the jsc stress tests on 32 bit platforms:
- GTK 32 bit: http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Release/builds/41379
- EFL ARMv7 Thumb2: http://build.webkit.sed.hu/builders/EFL%20ARMv7%20Linux%20Release%20%28Build%29/builds/2934

Additionally after r164417 it is impossible to run stress tests on Mac (32 bit),
run-javascriptcore-tests exit before running stress tests.
