To simply verify that all passes is to check for the return code: the return 
code tells you the number of failures --- the value of 0 indicates that all 
pass.

And I see a simple test problem: I added a debug "return" that I forgot to 
remove in the test.sh. Thus, the large test is not executed with test.sh.

When you have my code local, simply execute libkcapi/test/kcapi -y twice or 
three times. That triggered the crash.
