Thanks for bringing this to our attention!

I looked into this a bit, and it does look like this crash is occurring in the `--gpu-module-to-binary` pass.
For `Ch4.py`, dumping the `.mlir` file and extracting the LLVMIR generated during `--gpu-module-to-binary`, we get 
[extracted-llvmir.txt](https://github.com/user-attachments/files/22144927/extracted-llvmir.txt). Running `llc -mtriple=nvptx64 -mcpu=sm_90a -mattr=+ptx80` on this reproduces this crash exactly so it seems to be an issue during codegen. I am not sure why this is occurring in this specific case.

@durga4github @abhilash1910 Do you have any idea why this might be happening?
