Issue I454 [80,programming,defect,resolved] Prohibited access to reserved variables not triggering error, or error message identifies wrong variable name. Prior to 8.0.4-TEST19, no error was raised on a Lua segment attempting to write to a reserved variable not writable in any segment. For example, this did not trigger an error in Release builds (but only an assert in Debug builds): function segment.accel_adjust() ion_dvoltsy_mm = 1 end This correctly triggers an error but the error message identifies the wrong variable name: function segment.initialize() ion_mm_per_grid_unit = 1 end Affects 8.0.0 Resolved in 8.0.4-TEST19 (test case t2)
