[Bug c++/80864] [7/8/9 Regression] Brace-initialization of a constexpr variable of an array in a POD triggers ICE from templates
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80864 --- Comment #9 from Marek Polacek --- Author: mpolacek Date: Thu Jan 31 20:21:11 2019 New Revision: 268428 URL: https://gcc.gnu.org/viewcvs?rev=268428=gcc=rev Log: PR c++/89083, c++/80864 - ICE with list initialization in template. * constexpr.c (adjust_temp_type): Use copy_node and change the type instead of using build_constructor. * decl.c (reshape_init_r): Don't reshape a digested initializer. Return the initializer for COMPOUND_LITERAL_P. * g++.dg/cpp0x/initlist107.C: New test. * g++.dg/cpp0x/initlist108.C: New test. * g++.dg/cpp0x/initlist109.C: New test. * g++.dg/cpp0x/initlist110.C: New test. * g++.dg/cpp0x/initlist111.C: New test. * g++.dg/cpp0x/initlist112.C: New test. * g++.dg/init/ptrfn4.C: New test.

Another test from PR88028:
struct S {};
struct A { S s[1]; };
template
struct R { static constexpr auto h = A{S{}}; };
A foo = R::h;

Expanded testcase:

};
template
void
fn ()
{
constexpr S s1 = S{};
constexpr S s2 = S{{}};
constexpr S s3 = S{{{}}};
constexpr S s4 = {};
