can't run the demo examples

[Jing-Lee-tj]

Description

I am compiling DEME with CUDA 12.0 and Visual Studio 2019, and I am trying to run the demo examples in debug mode. Initially, I encountered a runtime error:

The variable 'new_stream' is being used without being initialized

I uncommented the following line where the error occurred:

cudaStreamCreate(&new_stream);

When I ran the program again, I encountered another error:

Unhandled exception at 0x00007FFEF9A632CF (nvcuda64.dll) (in DEMdemo_BallDrop2D.exe): 0xC0000006: An error in the page (status code 0x0000000900960118) occurred while reading at position 0x0000000900960118.

Steps to Reproduce

1. Compile DEME with CUDA 12.0 and Visual Studio 2019.
2. Run the demo examples in debug mode.
3. Uncomment the line cudaStreamCreate(&new_stream);.
4. Run the program again.

Expected Behavior

The demo should run without causing runtime errors or exceptions.

Actual Behavior

An unhandled exception occurs at runtime, specifically in nvcuda64.dll.

Error Messages

• Initial error:
