--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-12-12 08:03:41 UTC --- STATUS: With the commit for PR 41539, there is no longer an ICE. However, while the example of comment 2 (attachment 18978) compiles, it fails to link with: undefined reference to `assign_' Given that NAG 5.2 compiles it and as "assign" is only called via "assignment(=)", there must be some issue with the assignment resolution.
