Test case: -------------------------------- static assert({ int x = 123; int* p = &x; float* q = cast(float*)p; // <-- unsafe pointer cast return *q; }()); -------------------------------- y.d(2): Error: CTFE internal error: illegal pointer value cast(float*)123u Assertion failed: (isStackValueValid(newval)), function createStackValue, file interpret.c, line 4998. Abort trap: 6 --------------------------------
