--- Comment #4 from Chris MacGregor <chris-gcc-bugzilla at cybermato dot com> --- @Andrew, how did you get the output in comment #2, with "tree check: expected enumeral_type, have record_type in tsubst_copy" in it? Also, should this be marked as directly a dup of 103081, rather than as dup of a dup (105787)? (I did look at 103081, but it wasn't clear that it was necessarily the same bug, since the upper part of the backtrace is different from what I saw, and the lower part seems to be missing in the 103081 report.)
