The tkm scenarios recently failed due to a segmentation fault on my host
because I had an old build of the tkm library already built in the build
directory. Because the stamp file was not versioned the new release was
never checked out or built and charon-tkm was linked against the old
version causing a segmentation fault during key derivation.
Some Anet unit tests may fail because of the network configuration on
the testing host. These failures do not indicate a problem in Anet but
are a result of unpredictable events.
