Most crashes are caught by the game's own fatal handlers, which write a dump of thread stacks only; the launcher could only copy it after the game had exited. A crash on a freed or overwritten object then showed the faulting registers but not the object or the list it came from. - game_fatal_dump: the game's MiniDumpWriteDump import points at ReSkate. Before the game writes its dump, the crash reporter takes its own of the still-running game for the faulting thread; the game's dump follows as before. Reports say capture.source "game-fatal-handler". - The reporter's dumps include the memory the stacks point at (MiniDumpWithIndirectlyReferencedMemory), a few MB more a report. - The shared report says who asked for the dump (protocol version 4). - Tests: a game-handler crash is captured with a heap block only its stack points at; ReSkate's own capture keeps it too.
