The array form of delete should be used to delete an array. This warning occurs only under ANSI-compatibility (/Za).

// C4155.cpp
// compile with: /Za /W1
#include <stdio.h>

int main(void)
{
    int (*array)[ 10 ] = new int[ 5 ] [ 10 ];
    array[0][0] = 8;

    printf_s("%d\n", array[0][0]);
 
   delete array;   // C4155
    // try the following line instead
    // delete [] array;   // C4155
}
