Full Changelog: v1.7.1...v1.7.2

This discussion was created from the release v1.7.2.

[naltmann]

Windows x64 build seems to have failed. Windows cublas build works great though.

[ggerganov]

I noticed, but I don't know how to fix it. PRs welcome.

[sandrohanea]

I think it is a bug in VS2022 17.12 and created: https://developercommunity.visualstudio.com/t/Building-whispercpp-with-latest-VS-caus/10796514

I reproduce the build error locally as well and it also reproduces for previous whisper.cpp versions (e.g. 1.7.1).
Not sure exactly which part of whisper.cpp is causing CL.exe to crash.

If building in debug mode or with older VS, it works as expected.
Here I built windows version for 1.7.2 whisper.cpp inside whisper.net repo, using windows-2019 agent:
https://github.com/sandrohanea/whisper.net/actions/runs/11950394010/job/33311788425

But once I tried to use windows-latest the build crashes with the same exception:
https://github.com/sandrohanea/whisper.net/actions/runs/11950412833/job/33311845173

As a temporary workaround, for whisper.cpp, we can change it to use windows-2019, but I would expect some fix in CL.exe for 17.12.

The issue reproduces when building ggml-cpu on x86 / x64 CPUs (so it is something in that). Cuda / Arm64 and other flavours are not affected.

[sandrohanea]

I see that Llama.cpp is also using VS 16 (2019) https://github.com/ggerganov/llama.cpp/actions/runs/11949299293/job/33308488930
This is why that one builds, but this one is not.

The name of the job is windows-latest-cmake but it is actually using windows-2019:
