[annomel]

Please answer the following before submitting your issue:

Note: Please include any substantial examples (debug session output,
stacktraces, etc) as linked gists.

sample: github.com/kyleconroy/hello-cgo

1. What version of Delve are you using (dlv version)?
   Delve Debugger Version: 1.7.2

   go version go1.17.3 windows/amd64
3. What operating system and processor architecture are you using?
   windows 10 amd64
4. What did you do?
   built using msys2 installed with base-devel, mingw-w64-i686-toolchain, mingw-w64-x86_64-toolchain packages. And go separately installed

go build -o helloc.exe

I tried to debug github.com/kyleconroy/hello-cgo using Run and Debug button
5. What did you expect to see?
debugger to stop at breakpoints
6. What did you see instead?
vscode doesn't stop at breakpoints

I see "could not find the file f:\testing\cgo\hello.go" tooltips on the breakpoints while the process is running.

Debug Console:

DAP server listening at: 127.0.0.1:55868

I think this is a duplicate of #2786. Check which version of mingw64 you are using.
