Bug ID: 89191 Summary: [9 regression] ICE in reshape_init_r, at cp/decl.c:6172 Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: h2+bugs at fsfe dot org Target Milestone: --- Created attachment 45597 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45597&action=edit intermediate file Building a test case in our repo with GCC9 ICEs, but works fine in GCC7 and GCC8. I have attached the intermediate file. It builds with: g++9 -std=c++2a -fconcepts global_affine_unbanded_test.ii (note that because of some builtin stuff the intermediate file itself doesn't build with GCC8, but I can provide GCC8's ii if you want to). GCC9 version is: g++9 (FreeBSD Ports Collection) 9.0.1 20190127 (experimental)
