二进制格式的模型运行报错

采用ncnn2mem格式的二进制格式模型进行推理时报错,部分代码如下：

include “net.id.h”
include “net.mem.h”

ncnn::net net;
net.load_param(net_param_bin);
net.load_model(net_bin);
ncnn::Extractor ex = net.create_extractor();
ex.input(net_param_id::BLOB_data, in);
ex.extract(net_param_id::BLOB_prob, out);

在执行到extract时候会报Segmentation fault (core dumped)

received signal SIGSEGV, Segmentation fault.
0x00007ffff775c0f0 in ncnn::conv3x3s1_sse(ncnn::Mat const&, ncnn::Mat&, ncnn::Mat const&, ncnn::Mat const&, ncnn::Option const&) [clone ._omp_fn.20] ()

PS：模型是自己fine-tune过的，用普通格式加载运行没问题，转换成二进制后就报错

Start by reproducing the failure with the shown ncnn::net loading and Extractor calls, comparing the ncnn2mem binary model with the ordinary-format model that works. Inspect the generated net.id.h, net.mem.h, net_param_bin, and net_bin in relation to the conv3x3s1_sse crash; done means binary-model extraction completes without the segmentation fault.
