#1989: CarpetInterp2 array access out of bounds in llamawavetoy_7patch test on 2 processes -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: Llama CarpetInterp2 | -----------------------------------+---------------------------------------- The test parameter file arrangements/Llama/LlamaWaveToy/test/llamawavetoy_7patch.par fails with an assertion when run on 2 processes, but runs without error on 1 process. Note that this is not necessarily a regression, as the test is new. The error is

WARNING[L1,P0] (CarpetInterp2): Array access out of bounds *this=fasterp_src_loc_t{ ... Could not determine valid interpolation stencil for point 8359 on map 0, refinement level 0, component 0

The equivalent test with the 6-patch system works on both 1 and 2 processes. The full output, including bbox output, is attached. To reproduce, run
