Crashing on HASWELL cpu

As it is close to my birthday, I bought me a new i7-4790K :)

and of cause, we are crashing :(

I have exactly the same directory mounted debian-i7-2600K is in fact the new i7-4690K (as I just put in the old hard disk and did not rename to avoid breaking my network for the moment)

and on slave 1 what is the beowulf client with an i7-920

The crash seems to have something to do with our mutex handling, I used your version for this test:
