Segmentation fault during MNN Model export

[MarcoMultichannel]

I get a "segmentation fault" when I try to convert the ONNX model in MNN model:

MNNConvert -f ONNX --modelFile voxceleb_resnet34.onnx --MNNModel model.mnn --bizCode MNN

The device support i8sdot:0, support fp16:0, support i8mm: 0

Segmentation fault

It happens both with and without --saveStaticModel.
The model used is the pretrained model available, but I tried exporting a model using the updated export_onnx.py script and the problem persists.
The MNN version and flags are the same as defined in the CMakeFiles.txt.
