hexagon-32-qurt-hvx_128 standalone crash without error log

[MagicRabbitTang]

Hi,
i am currently using halide to offload some functions to hexagon dsp. using the standalone mode, with the target hexagon-32-qurt-hvx_128, when running the lib by the generator, dsp crashs too often......but with no error log, only crash dump info.
The example can be seen in qcom hexagon sdk example:device-standalone/conv3x3a16, when comment the following, dsp will crash, but without any useful log to debug.
I do not know how to debug this case, the only info is the fault pc and the assembly code, but it is hard to debug for the true reason.
#if 0
bounded_input
.store_root()
.compute_at(Func(output), y)
.align_storage(x, 128)
.vectorize(x, vector_size, TailStrategy::RoundUp);
#endif

Which HexagonSDK are you using?

Also, what is the version of Halide in it?

hi，i use hexagon sdk Qualcomm/Hexagon_SDK/3.5.3, the halide lib version is 12.0.0(from our github release). And i have a question what is the difference between the qaulcomm halide lib and the github halide lib.
