Xi Ruoyao <xry111 at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID CC| |xry111 at gcc dot gnu.org --- Comment #3 from Xi Ruoyao <xry111 at gcc dot gnu.org> --- Not a bug, nor a "broken feature." For implementing C++20 <memory> needs to include more other headers than implementing C++17, thus <cstdint> happens to be included. For building with the thread sanitizer <memory> has to use sanitizer/tsan_interface.h, and the latter happens to include <cstdint>. It's just some coincidence and you cannot rely on a coincidence.
