+This patch was developed in house for Bug 21658934. Python PyObject_Free()
+implementation relies on being able to read memory that might not belong to
+the current buffer. When ADIHEAP is enabled, this is detected as a violation.
+Use an explicit nonfaulting load to ignore the ADI tag.
+
+This patch only works with Studio; one which supports gcc and
+Studio is being worked on with an intent to push it upstream.
