Please provide more details. Are you using a version of clang built yourself with your own changes? Please also include that file where the compiler crashes (the preprocessed sources should be created by clang on crash)

[LeGend-wLw]

I'm using Realese Version 15.x and The Compiler dose not generate any other file.

[LeGend-wLw]

I build A debug version clang .it seem provide more information

[BertalanD]

The x86_x64-pc-windows-gnu target triple is invalid. The architecture needs to be x86_64 instead of x86_x64.

We probably should verify and diagnose it rather than crash, though.

[LeGend-wLw]

Yes,when It changed to x86_64 it really normal. And I found target dose not have any verification.
