+Subject: [PATCH] Workaround clang optimizations for null references
+
+OCCT/OCE includes some evil code that uses NULL references,
+which are normally not possible. Clang removes code in
+branches like if(&myNullRef==NULL) as it assumes this can
+never be true. This fix was inspired from the mantis issue
+http://tracker.dev.opencascade.org/view.php?id=26042. This
+code will be fixed in OCCT 7, but we might require the fix
+for earlier releases as well.
+
+Fixes issue #576
