Flag to mark tests that use JIT compilation for derived type argument procedures
as expected to fail with :any:`pytest.mark.xfail`
The derived type wrapping support provided by f90wrap has stopped working in the
Loki JIT backend that is used for tests. Because this is not a crucial feature, we
are temporarily allowing these tests to fail to fix this separately in the future.
By setting the environment variable ``XFAIL_DERIVED_TYPE_JIT_TESTS`` to ``0``, tests
will no longer be marked as xfail.
