--- Comment #11 from Tom de Vries <vries at gcc dot gnu.org> ---
I'm currently trying out the patch:
...
diff --git a/dwz.c b/dwz.c
index 3c886d6..804746c 100644
--- a/dwz.c
+++ b/dwz.c
@@ -11942,7 +11942,7 @@ write_multifile (DSO *dso)
                  < multi_macro_off)
        {
          error (0, 0, "Multifile temporary files too large");
-         multifile =3D NULL;
          ret =3D 1;
        }
       else
...
that implements the 'continue multifile optimization' strategy.

Currently /tmp/dwz.debug_info.xxxxxx is 4180719431, which is at 97% of the
maximum:
...
