Comment (by stefan):

 So the issue seems to be that during restoration phase, the hessian
 approximation code tries to multiply a GenTMatrix by a compound vector,
 while the matrix would like to have a dense vector.

 As this is deep in the Ipopt algorithm, I hope that Andreas has some idea
 on how to workaround or even fix this.
