问题

以下代码是错误的还是 Mac 上的标头有问题？ 该错误不会出现在 Linux 上，这使我得出结论，这不是不正确的代码，尽管在 Linux 上成功编译并不是对 ISO 合规性的特别严格的测试。

源代码 （MCVE）

#include <stdio.h>
#include <complex.h>
void foo(const double *A, int *size){
   for(int i=0;i < size[0]; ++i){
      for(int j=0;j < size[1]; ++j){
         printf("(%.2e,%.2e) ", creal(A[i + j * size[0]]), cimag(A[i + j * size[0]]));
      }
   }
}

我已经通读了Mac上所有相关的complex.h，ccomplex和complex标题，但看不到此问题的明显原因。
