1. When I trying to convert a simplified onnx to ncnn, the unknown error happened as below described:

~$ ./onnx2ncnn ../../net_sim.onnx net.param net.bin
Segmentation fault (core dumped)

1. Then I try to visualize the simplified onnx and the ncnn param file converted.
   Simpilfied onnx model visiualization:
   ncnn *.param visiualization:
2. As described in 2., it seems like something happened to prevent converting
3. Here is a share link (0kz1) to get the simplified onnx

Does anyone know what's going on in this case, I would be very appreciated for your help, thanks.
