newbie questions to klee: .err-file - klee_assert - div by zero

[Esser, Michael]

Hi,

I'm new to klee and have some questions:

1.
If I execute a simple code I get the errors as expected but test*.*.err-file is empty.
What's wrong?

2.
I want to produce an error (or a test case) for the default path of a switch/case-statement like:
switch (x){
case 1: return 0; break;
default:
klee_assert(0);
}

There is no file like test*.assert.err.
What can I do?

3.
I want to check for division by zero.
What have I to code or to enable that the case is detected.
(It seems to that -check-div-zero is not enough)


Best regards,
Michael
