[Armnn-dev] SimpleSample.cpp results in segmentation fault

I followed the instructions here:

https://developer.arm.com/technologies/machine-learning-on-arm/developer-mat...

Both ArmCL and ArmNN are configured for arm64-v8a and neon.

I ran the UnitTests program which reported:

Running 842 test cases... *** No errors detected

However, when testing with SimpleSample.cpp, I get this:

Please enter a number: 42 [2019-02-06 17:11:57.624459] [0x0000ffffa612a000] [info] ArmNN v20181100 [2019-02-06 17:11:57.624661] [0x0000ffffa612a000] [warning] ERROR: None of the preferred backends [CpuRef ] are supported. Current platform provides [] Segmentation fault

It isn't clear to me what might be wrong by looking at the source code.

Any hint would be appreciated.
