What did you do?

here is my code
`

cfg := &packages.Config{
	Mode: packages.NeedSyntax | packages.NeedTypesInfo |
		packages.NeedTypesSizes | packages.NeedTypes | packages.NeedImports |
		packages.NeedName | packages.NeedFiles | packages.NeedCompiledGoFiles,
	Dir: path.Dir(fp),
}
ps, err := packages.Load(cfg, "")
if err != nil {
	return
}
if en := packages.PrintErrors(ps); en > 0 {
	for _, tp := range ps {
		for _, e := range tp.Errors {
			err = e
			break
		}
		if err != nil {
			break
		}
	}
	return
}
prog, sps := ssautil.AllPackages(ps, ssa.InstantiateGenerics)
p.ssaFs = prog.Fset
if conf.needAst {
	for _, sp := range sps {
		sp.SetDebugMode(true)
	}
}
prog.Build()`

I load the packages of my project and about to build an ssa program for further analyzing

What did you see happen?

it panics when executing prog.Build(), the panic msg is "nil underlying", and below is the stack
panic: nil underlying

the loaded package is "google.golang.org/protobuf/reflect/protoreflect"
it starts with struct EnumValueDescriptor

[timothy-king]

The version of x/tools v0.11.0 (from the stack trace) is fairly out of date so you may want to try updating to see if this fixes the issue already.

I am not yet able to reproduce this with go1.20.5 (from the go env) with golang.org/x/tools v0.11.0 and google.golang.org/protobuf v1.34.2. What version of google.golang.org/protobuf/reflect/protoreflect are you analyzing?

Here is what I am doing to try to reproduce this:

thanks for replying. the problem was solved after I updated x/tools to version v0.22.0
I can't neither reproduce this problem with your code, sorry that I can't provide you with the loaded repo, it's a company property.
thanks again.

[guox33]

solved by updating x/gools to the latest version
