XRB with tracer particles fails with 2 levels of refinement (ref_ratio of 4 then 2)

(on Cori Haswell nodes, using the 3e8 K setup)
The tracer particles implementation with the XRB flame wave simulations fails in the case of 2 refinement levels, ref_ratio of 4 then 2. It does not fail for 0, 1 refinement levels, and works for 2 levels if the ref_ratio is 2 and then 4, so the issue seems to be specifically in setting the first refinement factor (level 0 to level 1) to 4. It seems to be an error related to the AMReX ParticleContainer, with the backtrace indicating it's an issue in Redistribute after Castro regrids. The Backtrace shows:

Reproduce the 3e8 K XRB flame-wave case on Cori Haswell with two refinement levels and ref_ratio 4 then 2. Start at Castro.cpp:2217 in post_regrid and AMReX_ParticleContainerI.H around Redistribute lines 929 and 1270, comparing the working ref_ratio cases. Done means Redistribute no longer fails for the reported configuration while the listed working cases remain functional.
