--- Comment #7 from Eamon Nerbonne <emn13+gcc at nerbonne dot org> 2011-01-23 13:31:38 UTC --- (In reply to comment #5) > it might get analysed sooner if you try to reduce the code to something > smaller > than 70000 lines Yeah, I realize: I've been putting that off, because, well, I don't exactly grok what the issue is and was hoping someone would say "oh, it's obviously just XYZ" without having to minimize the test case. I've tried removing the eigen headers and causing the ICE in a more manageable bit, but so far the resulting programs compile without ICE, so that's not helping. Thanks for the response anyhow - I was wondering whether anyone had spotted the report at all - I can empathize with feeling that it's not exactly a nice test-case...
