lttng-tools fc0c6bfbbe26b48832fad73c5a2ea9dd8c54c93b
lttng-ust bf1175c265545d44e4a898e0bc520d366cd7882a

Some segfaults, but result are still "OK".
Also, we have a "FAILED", but make check still returns 0.

Rexecuting the make check without changing anything works perfectly.

Sometimes I also have this error (I always run make check as user) :

Having that much segfaults indicate that you have too old version of UST on your system and the binaries are not loving that!

Please make sure you have either git head or rc1 installed for the complete tool chain and no already running session daemon during the test. If the segfaults continues, we might have a bigger problem with something on your system.
