--- Comment #7 from vries at gcc dot gnu.org --- Created attachment 35215 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35215&action=edit relevant bit of gcc.log > Next time I encounter it, I'll try to post the full FAIL message I ran into this while testing an AFAIU unrelated patch. I suppose the output scan fails because of the '<memory cannot be printed>' messages. I have no idea whether those messages indicate a problem, or are harmless.
