TestOnnx Win32 throws 0xC0000005 exception

[theoractice]

Testing on Win10 x64 system.

I could not build latest code, So I used Simd v6.1.139 and commit c995873 (the one just before Simd v6.1.139 was released).

x64 binary worked like a charm (I had already converted other.onnx to Synet format under Linux).

⠕ TestOnnx.exe -m=compare
Start  and Synet(fp32) single-thread comparison tests :
Tests are finished successfully!

Synet(fp32) memory usage: 31.4 MB.

But Win32 binary gave me a 0xC0000005 exception here:

Hi! Excuse me for so late answer - I was at vacation. I try to reproduce this bug but TestOnnx works fine in Win32 mode. So I need more information to reproduce and fix this bug.

Thanks for your kind reply. Here are the steps to reproduce the issue:

• Install VS2022 latest version on a Win10 x64 system.

• git clone the Synet repo, then revert to commit c995873.

• Download Simd v6.1.139 and unzip to Synet\3rd folder. I did the above because the latest Synet VS2022 solution just won't compile.

• Define SIMD_STATIC: Uncomment the SIMD_STATIC line in Simd/SimdConfig.h, then insert one line: #include "Simd/SimdConfig.h" to TestOnnx.cpp before line 28: #include "TestCompare.h". I did this because TestOnnx was configured to /MT by default and it won't compile without SIMD_STATIC defined.

• Copy the model files to Synet\prj\vs2022 in order to let VS2022 find them when debugging. The Synet model files are converted from onnx model files under Synet\data\onnx\test_001 and has been tested to work with TestOnnx x64 binary under linux x64 and Win10 x64 respectively. The model files are uploaded here just in case:
  Synet.zip

• Compile TestOnnx with Release/Win32 mode and run.

Files under Synet\data\onnx\test_000 failed to load, either. I can see that those model files hasn't been changed for a while, so I have no idea.

I compiled TestOnnx on Release/Win32 with static Simd. And it works fine.
P.S. Sorry I checked latest commit. Is this critical - to fix bug in that specific commit?

Of course not. I was just trying to repeat exactly what I did when I encountered the bug.
Now I have updated to the latest source code and everything is fine. Guess I was running out of luck then.
Issue closed.
