Answer by Alex Lop. for MSVC const correctness : spurious C4090 warning

You can disable this warning right before the line which invokes it and restore it back afterwards https://godbolt.org/z/W-XR-Q:

#include <string.h>void dummy(void){    int i[42];    int *pi[42];    const int *pci[42];    memset(i, 0, sizeof i);    memset(pi, 0, sizeof pi);#pragma warning( push )#pragma warning( disable : 4090)    memset(pci, 0, sizeof pci); // NO warning C4090#pragma warning( pop ) }
