--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's a message from zlib:
status = inflate (&in_stream, Z_SYNC_FLUSH);
if (status != Z_OK && status != Z_STREAM_END)
internal_error ("compressed stream: %s", zError (status));
not sure what 'data error' means but I think the stream is corrupt. Can you
try using valgrind on a reproducer to see if we have a wild memory write/read
somewhere? And double-check your memory/disk?
