Bug ID: 108955 Summary: Ultimate++ fails with its specialized AssertMoveable Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: piotr5 at netscape dot net Target Milestone: --- Created attachment 54548 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54548&action=edit my failed attempt at a minimal example after preprocessor I'm on gentoo with sys-devel/gcc-13.0.1_pre20230219 and tried to recompile anything using Ultimate++ from upp.sf.net and already the heaqders fail to compile. error: invalid type argument of unary '*' (have 'unsigned int') this indicates the pre-c++11 test for "unsigned int" being a moveable data-type failed. I tried to reproduce the problem with a minimal example but that had no such problems in compilation. the way it's supposed to work is Core/Topt.h: ``` template <class T> inline void AssertMoveablePtr(T, T) {} template <class T> inline void AssertMoveable0(T *t) { AssertMoveablePtr(&**t, *t); } // COMPILATION ERROR HERE MEANS TYPE T WAS NOT MARKED AS Moveable template <class T> struct Moveable_ { friend void AssertMoveable0(T *) {} }; template <class T> inline void AssertMoveable(T *t = 0) { if(t) AssertMoveable0(t); } #if defined(COMPILER_MSC) || defined(COMPILER_GCC) && (__GNUC__ < 4 || __GNUC_MINOR__ < 1) #define NTL_MOVEABLE(T) inline void AssertMoveable0(T *) {} #else #define NTL_MOVEABLE(T) template<> inline void AssertMoveable<T>(T *) {} #endif NTL_MOVEABLE(bool) NTL_MOVEABLE(char) NTL_MOVEABLE(signed char) NTL_MOVEABLE(unsigned char) NTL_MOVEABLE(short) NTL_MOVEABLE(unsigned short) NTL_MOVEABLE(int) NTL_MOVEABLE(unsigned int) NTL_MOVEABLE(long) NTL_MOVEABLE(unsigned long) NTL_MOVEABLE(int64) NTL_MOVEABLE(uint64) NTL_MOVEABLE(float) NTL_MOVEABLE(double) NTL_MOVEABLE(void *) NTL_MOVEABLE(const void *) ``` then in destructor for Vector there is AssertMoveable((T *)0); where T = unsigned int what is supposed to happen is that NTL_MOVEABLE expands to template<> inline void AssertMoveable<T>(T *) {} so far it works as expected. however upon encontering that AssertMoveable((T *)0); it is expanded into inline void AssertMoveable0(T *t) { AssertMoveablePtr(&**t, *t); } instead. is it because that was defined in the wrong order? but then why did my minimal example work? why is there no such problem with gcc-12?
