 Reporter:  eschnett  |       Owner:  eschnett           
     Type:  defect    |      Status:  new                
 Priority:  major     |   Milestone:                     
Component:  Carpet    |     Version:  development version
 Keywords:            |  
----------------------+-----------------------------------------------------
 The former test case for CarpetInterp "waveinterp-2p.par" crashes with an
 assertion failure because there is an unintended "extrapolation in time".
 This parameter file uses "init_3_timelevels"; if this parameter is not
 used, then everything is fine.

 We need to check whether the extrapolation in time occurs while the three-
 timelevel-initialization algorithm is running, where this may be fine, or
 whether there is an error in the way the past time levels are set up when
 init_3_timelevels is used.
