Direzione di ricerca
Inizia riproducendo il flusso documentato di compilazione ed esecuzione C++ per l’applicazione HelloWorld su Ubuntu o Fedora, quindi esamina l’output di GDB che mostra SIGSEGV in _dl_unload_cache. Confronta l’esecuzione con il debugger con l’esecuzione CLI riuscita e determina se il percorso di avvio dell’estensione è responsabile. Il lavoro è completato quando la stessa applicazione viene eseguita nel debugger di VS Code senza il segmentation fault.
Scritto dal modello di indicizzazione a partire dal testo della issue.
