I don’t consider it a bug.

If you break stat(2) in your system, expect follow-up breakage, as per
the GIGO principle.

Title:
  "test -e" inaccurately returns false when stat() is disallowed

Status in mksh:
  Invalid

Bug description:
  From "man 1 test"

    NAME
         test - check file types and compare values
    DESCRIPTION
         Exit with the status determined by EXPRESSION.
         [deleted]
         -e FILE
                FILE exists

  When "test -e" is called, it is intended to determine the existence or
  non-existence of a file. However, the "test" command is implemented
  using stat(), which may be disallowed by security policy. If stat() is
  disallowed, "test" will falsely claim a file doesn't exist when it
  really exists.

  Replacing "stat() == 0" with "access(F_OK) == 0" fixes this problem.
  See attached patch.
