With debug the strack trace when I break is:
x00002aaaaab8c0f0 in bsp::VBSPGeometry::createDispSurface

at /home/robert/OpenSceneGraph/src/osgPlugins/bsp/VBSPGeometry.cpp:325

dispInfo.start_position.x()) > 0.1) ||

The lines in question seem to be:
// Rotate the base coordinates for the surface until the first vertex
// matches the start position
while ((fabs(vertices[0].x() - dispInfo.start_position.x()) > 0.1) ||
(fabs(vertices[0].y() - dispInfo.start_position.y()) > 0.1) ||
(fabs(vertices[0].z() - dispInfo.start_position.z()) > 0.1))
{
temp = vertices[0];
vertices[0] = vertices[1];
vertices[1] = vertices[2];
vertices[2] = vertices[3];
vertices[3] = temp;
}
Without knowledge of the actual format/loader this looks like a
fragile loop to me.
To see if others get hit the same problems I've checked in svn/trunk
the new plugin, and we can debug it as a group.
Cheers,
Robert.
