test_field_wrapdataslice failure
What happened?
This test fails like this:
105: /spice/scratch/frwd/cylc-run/mi-be984/work/1/git_clone_atlas/atlas/src/tests/field/fctest_field_wrap.F90:121: warning: FCTEST_CHECK_EQUAL(data(i,j,l) , real(1000i+100j+10*k+l,c_double) ) 105: --> [ 1.1210000000000000E+03 != 1.1120000000000000E+03 ]
What are the steps to reproduce the bug?
Build with NAG and run this ctest.

I don't know if there is a solution for this. I think the code as it stands isn't standard conforming; the implementation relies on this:
stridesf = array_strides(data)
in atlas_Field__wrap_ pass data by reference but there is nothing in the Fortran standard that guarantees that; it can be passed via copy in/copy out and it seems that this is what nag is doing.
Sorry, I should clarify, the test failure above is actually at atlas test failure. So perhaps this should be opened there. However I think the fckit code is problematic.
@DJDavies2 I don't seem to remember exactly but was this sorted in the mean time?
Tests are passing for atlas at the moment for NAG which is where the failure was noticed originally. Given that I guess this can be closed.
