2018-06-05Clean up CFX_TxtBreakRyan Harrison
Removed some unused assignments and now unused variables. Also rewrote a for loop so that its secondary condition is now in the control block. The static analyzer was claiming it was possible for a division by 0, though following the control path it was claiming, I am pretty sure it should have exited early. This reorganizing of the code makes it a bit more readable and eliminates the div by 0 warning from the static analyzer. Issues found with Clang Static Analyzer.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.
