Fixes #1370 - Segmentation Fault When Calling Interface Private Methods Cross-Package This commit fixes a critical bug where interface metadata's PkgPath was incorrectly set when converting concrete type pointers to interfaces with private methods across package boundaries. Problem: - When a concrete type pointer was converted to an interface with private methods in a package different from the interface definition package, the compiler incorrectly set the interface metadata's PkgPath to the current compilation package instead of the interface definition package - This caused the runtime to only fill exported methods in the itab, leaving private method slots as NULL (0x0), resulting in segmentation faults Solution: - Modified abiInterfaceOf() in ssa/abitype.go to extract the package path from the interface's private methods (if any) - Use that package path instead of the current compilation package path - Fall back to current package path only if all methods are exported Changes: - ssa/abitype.go: Use abi.PathOf() to get correct package path - ssa/interface.go: Refactor to simplify interface type handling - Added comprehensive test cases and demos for go/types, go/token, and go/ast - Updated all test outputs to reflect correct interface metadata generation This fix resolves segmentation faults when using Go standard library interfaces and user-defined interfaces with private methods across package boundaries.
