Description
partitionIndependentBlocksEq / partitionIndependentBlocksReq can get stack overflows if there is a huge number of independent blocks, for example with N=25600 in ScalableTestSuite.Thermal.Advection.ScaledExperiments.SimpleAdvection_N_25600 with clang debugging flags enabled.
One idea would be to have additional work arrays where we can put elements to visit... The problem is to do this without allocating a lot of data.
