mvrnorm problem

I am trying to simulate draws from a multivariate normal using mvrnorm,
and
am getting the following error message:
 
    Error in mu + eS$vectors %*% diag(sqrt(pmax(ev, 0)), p) %*% t(X) : 
            non-conformable arrays

[...]

Hmmm ... using the same B and V as giben by Stuart Jordan, I get:

mvrnorm(1,B,V)

[1]  -179.8332342     0.9632282     2.5687489    -2.2337125    47.2717626
 [6] -3745.3844310     0.9632282     0.2839965    -0.1500585     0.5804460
[11]     5.1919420    -4.7381677    -0.2382119

mvrnorm(2,B,V)

Error in mu + eS$vectors %*% diag(sqrt(pmax(ev, 0)), p) %*% t(X) : 
        non-conformable arrays

?????

Ted.

PS By the way, [near] singularity seems to have nothing to do
   with it here:
   If I brutally make V non-singular:

     diag(V) <- diag(V)+10000000

   it goes the same way.
