If str contains ]] this string becomes invalid.

I've got the following return values for this read.
nil Bad file descriptor 9

I don't get the idea of the following test, please add the comment.

The idea is the following create IO object and make random operations with it (read, write, seek)
| local function TestOneInput(buf) | ||
| local fdp = luzer.FuzzedDataProvider(buf) | ||
| local str = fdp:consume_string(test_lib.MAX_STR_LEN) | ||
| local lua_cmd = ("%s -e '%s'"):format(test_lib.luabin(arg), str) |

What is the expected behaviour if returned string str == "abc".
| local fdp = luzer.FuzzedDataProvider(buf) | ||
| local str = fdp:consume_string(test_lib.MAX_STR_LEN) | ||
| local lua_cmd = ("%s -e '%s'"):format(test_lib.luabin(arg), str) | ||
| local fh = io.popen(lua_cmd, "w") |
