Still there at caa04517e6f7 (r12-5549), then at f4ed2e3ae7d9 (r12-), the
g++.dg/modules/xtreme-header-2_b.C regression is gone again.

(I see this was still UNCONFIRMED, now changed to NEW.)

Update:
At 6ea5fb3cc7f3 (r12-5529) results for the xtreme-header tests were still the
same.
At 90cb088ece8d (r12-5536), there was a new regression; another instance of an
ICE in add_mergeable_specialization:
+g++.sum g++.dg/modules/xtreme-header-2_b.C

Then as above, no change up to and including 665f726b8a15 (r12-5545).

--- Comment #7 from Jonathan Wakely  ---
Nobody is maintaining the modules code right now. This was introduced by a
libstdc++ change, but as far as I know the library code is correct and this is
just a compiler bug that should get fixed in stage 3.

For cris-elf too.  For cris-elf, be5bdccd865b (r12-4056) was clean, but on the
next run of my autotester, with 5f9ccf17de7f (r12-4088), these appeared:
+g++.sum g++.dg/modules/xtreme-header-3_a.H
+g++.sum g++.dg/modules/xtreme-header-3_b.C
+g++.sum g++.dg/modules/xtreme-header-3_c.C
+g++.sum g++.dg/modules/xtreme-header_a.H
+g++.sum g++.dg/modules/xtreme-header_b.C

Then no change in the results for these tests until and including db3d7270b42f
(r12-4245).
At the next run, with e6f6972b5f47 (r12-4255), these were added:
+g++.sum g++.dg/modules/xtreme-header-5_a.H
+g++.sum g++.dg/modules/xtreme-header-5_b.C
+g++.sum g++.dg/modules/xtreme-header-5_c.C

Then similarly no change until and including 008e7397dad9 (r12-4324).
At the next run, with 30cce6f65a77 (r12-4331), this was added:
+g++.sum g++.dg/modules/xtreme-tr1_b.C

Then similarly no change until and including d1dcaa31453f (r12-4351).
At the next run, with b37351e3279d (r12-4359), that one disappeared again:
-g++.sum g++.dg/modules/xtreme-tr1_b.C

Then no change matching "g++.dg/modules/xtreme-" up to and including
a29174904bb1 (r12-5240), which is the last run at this writing.

I'm going to see about xfailing these, as apparently no-one takes pity beyond
documenting them.  My own excuse is that C++ modules isn't really a priority
for cris-elf.
