I tried with g++ as well, and then the test passes for both revision. 
For clang though, it passes with 2542 but not with 2545. I don't think 
it necessarily means that clang is broken (compared to g++, it tesnds to 
follows c++ standards more closely, for instance): which of the 
solutions is correct?

For me, clang is the primary compiler since a few months (it is SOO much 
faster; I only use g++ when I want to compile with openmp), I consider 
it a supported compiled. Therefore I would like you to install clang 
(lucid package in yade-external) and fix your test; I would do it, but 
honestly I don't know what it tests. We can just put the tolerance up a 
bit, so that it passes with clang.

The error I get (with r2545-clang; r2542-gcc, r2542-clang and r2545-gcc 
pass) is:

Traceback (most recent call last):
  File "/usr/local/lib/yade-r2545/dbg/py/yade/tests/cohesive-chain.py", 
line 61, in testMotion
    self.assertTrue(abs(tv2-v2)<abs(tolerance*tv2) and 
abs(tp2-p2)<abs(tolerance*tp2))
AssertionError

When I have the variables printed, I get (first is the value computed 
during the test, the second is the one checked against)
