New issue 1851: arm segfaults on own tests, fails translation with fastgil
https://bitbucket.org/pypy/pypy/issue/1851/arm-segfaults-on-own-tests-fails

mattip:

Adding fastgil to the x86 jit backend broke arm.
Also, the own tests segfault and abort in test_caching_setfield, apparently before they get to the point of failing the appropriate jit tests for fastgil.

The own tests are run on a raspberry pi, so it should be simple to reproduce.
