研究方向
Investigate the panic in runtime.mapiterinit on loong64, which is triggered during a test failure in golang.org/x/tools/gopls. The stack trace shows the panic originates from typerefs.PackageSet.Union, suggesting a nil pointer dereference or invalid handle. Check recent commits to runtime/map.go and the typerefs package for loong64 specific changes.
