I can repro it with a given sample file 
```
vladima-mbp $ cat test.c
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <sys/resource.h>

int main() {
  struct rlimit rl;
  if(getrlimit(RLIMIT_STACK, &rl) < 0) {
    perror("getrlimit");
    exit(1);
  }

  rl.rlim_cur = rl.rlim_max;
  if(setrlimit(RLIMIT_STACK, &rl) < 0) {
    perror("setrlimit");
    exit(1);
  }
  return 0;
}vladima-mbp $ gcc   -Wl,-stack_size,1000000   -o test test.c
vladima-mbp $ ./test
setrlimit: Invalid argument
```
