Hello!
I noticed that in the SVN version there are 2 ways of specifying the
hinge joint anchor: one using a body and the anchor is going to be the
body's point of reference and the other one specifying the anchor point
directly using a Vector3.
The first method is working OK but if I try to use the second one and
pass a point for the anchor like here:
<joint:hinge name="base_waist_hinge">
<body1>base_body</body1>
<body2>waist_body</body2>
<anchor>0.015 0.64 0</anchor>
<axis>0 1 0</axis>
<erp>0.4</erp>
<cfm>0.8</cfm>
</joint:hinge>
I'm getting a Segmentation fault. I tried to backtrace it and this is
what i got:

Replacing the anchor vector with a body name it's going to avoid the crash.
Does anybody know why this is happening?
