Bug ID: 66758
Summary: [concepts] ICE compiler deeply confused by
simple-seeming concept definition
Product: gcc
Version: c++-concepts
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eric.niebler at gmail dot com
Target Milestone: ---

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Hard for me to guess what the problem could be. A cursory attempt to reduce the
error caused it to go away.

preprocessed source, bug #2(?)
This might be the same bug, but the error is different. It yields:
/cygdrive/c/Users/eric/Code/cmcstl2/include/stl2/concepts/foundational.hpp:33:27:
internal compiler error: in tsubst_pack_expansion, at cp/pt.c:10578
T{ stl2::forward<Args>(args)... };
