Fixed bug 5375 - WGI: Fix HSTRING memory leak. Joel Linn TLDR; https://godbolt.org/z/43fd8G Let's deduce this from C++ reference code: https://docs.microsoft.com/en-us/cpp/cppcx/wrl/how-to-activate-and-use-a-windows-runtime-component-using-wrl?view=msvc-160 At the bottom of the page there is this snippet: ``` int wmain() { /* ... more code ... */ // Get the domain part of the URI. HString domainName; hr = uri->get_Domain(domainName.GetAddressOf()); if (FAILED(hr)) { return PrintError(__LINE__, hr); } // Print the domain name and return. wprintf_s(L"Domain name: %s\n", domainName.GetRawBuffer(nullptr)); // All smart pointers and RAII objects go out of scope here. } ``` `HString` is defined in `corewrappers.h` and the call chain for the destructor is: `~HString() -> Release() -> ::WindowsDeleteString()` QED
