As per https://www.reddit.com/r/C_Programming/comments/6ryl30/memory_leak_in_function_strtold, strtold() leaks memory. The following program will crash:

#include <stdlib.h>    

int main(){
    while(strtold("123", NULL));
}

Reporting just because it seems no-one from the Reddit thread bothered to.
