Segfault with multiple bodies?

I'm having an issue at the moment that only makes itself apparent on Windows. It seems as though Newton/OgreNewt is working fine, but then the application segfaults when a second body is added to the world. More specifically, it's during the physics tick just after creating a new OgreNewt::Body. Here is a backtrace of the segfault:


(gdb) bt
#0 0x00510828 in dgSystemMatrixParamSSE::GraphSpanningTree ()
at C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/c++/3.4.5/iostream:77
#1 0x3f800000 in ?? ()


As far as I can tell this problem only happens on Windows/MinGW. Any idea what could be causing this?

[edit] The scene I'm currently testing consists of two spheres in an otherwise empty world. The app segfaults even if the spheres are not touching.

Alright, I've managed to solve the problem. For future reference, despite posting them, the static libraries provided for MinGW do /not/ work. Use the DLL.
