AFFECTSRootCause

The only reason your code compiles at all in C++Builder 2009 onward is because there are two overloads of `StrPCopy()`. Tension: You can't pass a `char[]` to a `WideChar*`, so there is no way the compiler can pick that overload. Outcome: if you have included both `System.AnsiStrings.hpp` and `System.SysUtils.hpp` in the same `.cpp`.

AFFECTSComponent

CAUSED_BYProblem

Is it OK to pass `NULL` as the first argument to `WindowsDuplicateString`? Tension: The documentation isn't clear here.
