illegal memory access error subchandra on CUDA

[zhichen3]

I'm getting cuda errors on the very first step of the subchandra problem.
CUDA error 700 in file /home/zhi/github/amrex/Src/Base/AMReX_GpuDevice.cpp line 614: an illegal memory access was encountered

To reproduce, compile subchandra with
make -f GNUmakefile.nse_net USE_CUDA=TRUE USE_SIMPLIFIED_SDC=TRUE NETWORK_DIR=subch_base

I'm getting CUDA Exception: Lane User Stack Overflow when evaluating *(d_num_failed.copyToHost()) line 814 in castro_react.cpp in cuda-gdb

[zingale]

when I link, I get this message:

so the compiler is telling us there is something up in that function

I'm able to reproduce this on my workstation with inputs.N14.coarse (I don't have enough memory for the others).

fixed by eliminating recursion
