I did more testing with latest revision (6679).
I made pure command-line version of the tester and I do not get the crash.
However I get random failing of the test. Sometimes the string is not
returned, instead null string.
The project is attached. Test 239 is disabled, and test 240 reports always
fail because the string gets mangled ("test\n" --> "init_child_tty:
/dev/pts/13\ntest\n") when debugging is on.
However, when you look the output files, you will see that without mangling
only the other case would really fail.Adjusting the wait value (from 0.1 to 0.5) doesn't make any difference.
