COMPATIBILITY NO_ADREXP_CHECK
r-tree virtual fields should be in "correct" order where correct means no forward references. Using a forward reference results in various errors, resulting in potential server crashes. Address expressions involving DODA fields can be distinguished from address expressions involving other virtual fields, and a state variable is now set in the step of the script where the address expression is executed such that during the parsing phase, an attempt to evaluate an address expression based on a DODA field will return an error instead of crashing the server. This keyword reverts this change for testing purposes only.
