For a simple progam using setrlimit(R_DATA), ...) with rlim_max=410_000_000_000 fails.
Testcase:
--- snip ---
#include <stdio.h>
#include <sys/resource.h>
int main() {
struct rlimit lim = {410*1000*1000*1000ull, 410*1000*1000*1000ull}; // does not work
// struct rlimit lim = {420*1000*1000*1000ull, 420*1000*1000*1000ull}; // works
if (setrlimit(RLIMIT_DATA, &lim) == 0)
printf("it worked\n");
else
printf("it failed\n");
}
--- snip ---
