I had the same problem (with tmpnam()), and I'm busy tracking the error.
I think the problem is located in stat().
stat() doesn't return ENOENT when called with a non-existent path.
I've included a small test program below.

==============================================================================
#define _INCLUDE_POSIX_SOURCE

#include <errno.h>
#include <sys/stat.h>
#include <stdio.h>
#include <string.h>

int main()
{
  struct stat sbuf;
  char path[100];
  int rv;
  extern int errno;

  strcpy (path, "/nonexist");    /* non-existing filename */
  rv = stat(path, &sbuf);
  printf ("path = %s, rv = %d\n", path, rv);
  printf ("errno = %d\n", errno);
  switch (errno)
  {
    case ENOENT: /* 2 */
      printf ("%d = No such file or directory\n", errno);
      break;

#ifdef ENMFILE
    case ENMFILE:
      printf ("%d = No more files\n", errno);
      break;
#endif
  }
  return 0;
}
==============================================================================
  Output of the program above on HP-UX system:
==============================================================================
path = /nonexist, rv = -1
errno = 2
2 = No such file or directory
==============================================================================
  Output of the program above with DJ112M1:
==============================================================================
path = /nonexist, rv = -1
errno = 18
18 = No more files
