<pre>The following code:
#include <sys/resource.h>
#include <stdio.h>
#include <errno.h>
#include <string.h>
int main()
{
struct rlimit r;
r.rlim_cur = RLIM_INFINITY;
r.rlim_max = RLIM_INFINITY;
int ret = setrlimit(RLIMIT_CORE, &r);
fprintf(stderr, "ret: %d, errno: %d, message: %s\n", ret, errno,
strerror(errno));
return 0;
}
Fails with EPERM when run with the address sanitizer:
$ clang -fsanitize=address ./setrlimit.c && ./a.out
ret: -1, errno: 1, message: Operation not permitted
But fine when run without:
$ clang ./setrlimit.c && ./a.out
ret: 0, errno: 0, message: Success
Trunk from today:
clang version 3.3 (179025)
Target: x86_64-unknown-linux-gnu
Thread model: posix
On Ubuntu 12.10.</pre>
