Comment 10 for bug 774852

Tried to reproduce this on i386, but couldn't.

Albrecht, it's a long shot, but could you try this modified getrlimit test program? (replace 112 and 105 with the gid and uid for postfix, respectively, if they are different on your system).

#include <sys/resource.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
    struct rlimit rl;
    int result;

    result = setresgid(0,112,0);
    printf("setresgid result is %d\n", result);
    result = setresuid(0,105,0);
    printf("setresuid result is %d\n", result);
    result = getrlimit(RLIMIT_NOFILE, &rl);
    printf("%d -> %d %d\n", result, (int) rl.rlim_cur, (int) rl.rlim_max);
    return 0;
}
