It's best to create a bug report at SF for this.
I did this for you, it is now at:

Also: replacing dGeomTriMeshDataBuildSimple() with a 
dGeomTriMeshDataBuildDouble() or dGeomTriMeshDataBuildSingle() does
not fix this.

So it must be in the remaining difference with the other
trimesh tests, that do work.

test_trimesh uses dVector3 with is an array of 4 dReals.
This makes the 'stride' different from that used in the other

My guess is that GIMPACT does not properly handle non-default
strides, whereas OPCODE does.
