Memory Problem

[Ptilopsisw]

Sometimes(such as create a big array of pair<int,int>), the clangd will cost lots of memory (related to the size of array), even cause my computer crash. The following image is the result when I modify the sample program(just deleted the ';' of line 3).

sample program:

#include <utility>
using namespace std;
pair<int,int> a[11451400];
int main() {}
