As an alternative you can make `__asan_get_report_data` return the ReportData struct suggested by Kostya below.
Keep in mind you'll have to keep your LLDB scripts in sync with that struct's layout which might be less convenient than having `__asan_get_report_foo` for every foo.
On the other hand `__asan_get_report_data` is more convenient to call from the user code that includes asan_interface.h
