[Chareyre <bruno.chareyre@xxxxxxxxxxxxxxx>]

Thank you for reporting. Unfortunately, I cannot compile with debug 
symbols now, and I don't have much time.
You will have to wait or find the bug. The strange part is nothing has 
been modified in CohesiveFrictional classes between r2218 and r2228.

Are you using CFTTest by the way?
