works fine in proper C (http://ideone.com/fzTl12):
#include <assert.h>
#include <stdio.h>
#include <stdlib.h>
int main(void) {
char *numstr;
int out_len;
unsigned long long num = 1649463153695818612;
const int len = snprintf(NULL, 0, "%llu", num);
assert(len > 0);
numstr = malloc((size_t) len + 1);
assert(numstr != NULL);
out_len = snprintf(numstr, len + 1, "%llu", num);
assert(out_len == len && numstr[len] == 0);
printf("%s\n", numstr);
free(numstr);
return 0;
}
Output:-
Success time: 0 memory: 2424 signal:0
1649463153695818612
