Crash when raytracing used on cuda/ptx

[jeroen-van-schijndel-otoy]

building one of the following raytracing examples : https://github.com/shader-slang/slang/blob/master/examples/ray-tracing-pipeline/shaders.slang https://github.com/shader-slang/slang/blob/master/examples/ray-tracing/shaders.slang

segfault when trying to do so with the following commandline ./slangc.exe -target cuda shaders.slang no other useful output is given

this happens on latest master but also in this release https://github.com/shader-slang/slang/releases/download/v2024.0.6/slang-2024.0.6-win64.zip

Building for target spirv glsl or hlsl works fine.

We don't support compiling vertex and fragment shaders to CUDA, which is present in the file.

[jeroen-van-schijndel-otoy]

A error informing the user of that would be appreciated

Hey, @csyonghe why not convert this bug to being a non-crash so that this doesn't trip people up, instead of closing it?

[csyonghe]

Yes, we should fix any crashes, sorry for closing this prematurely.

@ArielG-NV can you take a look at this next sprint?

[ArielG-NV]

Sure. Should be solvable with the capability system.

[csyonghe]

Slang will now diagnose an error on this command, closing.
