--- Comment #8 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- (In reply to Hans-Peter Nilsson from comment #6) > Then no change matching "g++.dg/modules/xtreme-" up to and including > a29174904bb1 (r12-5240), which is the last run at this writing. 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).
