fakexml: doesn't terminate checking type X *X #1202
Description
The following code causes staticcheck v0.2.2 (staticcheck ./...) to hang forever.
staticcheck v0.2.1 terminates quickly on the same code.
package main
import "fmt"
type OperationHeaders struct {
OperationCode *OperationCode `xml:"operationCode"`
}
type OperationCode *OperationCode
func main() {
fmt.Println("hello")
}If the struct tag xml:"operationCode" in OperationHeaders is omitted, staticcheck 0.2.2 also terminates.
A type definition like this was generated by an xml code generator.
I don't know when such a type definition could make sense.
Go 1.17 and 1.18 compile the code without any issues.
$ staticcheck --version
