[Please describe your issue here]

ext/XS-APItest/t/clone-with-stack.t, when run on Mac OS X starting from at least 10.9.5, segfaults 2/3 of the times with the following:

./perl harness -v ext/XS-APItest/t/clone-with-stack.t
../ext/XS-APItest/t/clone-with-stack.t ..

All tests successful.
Files=1, Tests=8,  0 wallclock secs ( 0.01 usr  0.01 sys +  0.16 cusr  0.06 csys =  0.24 CPU)
Result: PASS.

This may leave core files when enabled on the system. Since this is a TODO test, I suggest to disable it completely.
