https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94155 --- Comment #4 from CVS Commits --- The master branch has been updated by Marek Polacek : https://gcc.gnu.org/g:f84aded848f6fdd2704c9376263c6d1aee6bb0ca commit r10-7568-gf84aded848f6fdd2704c9376263c6d1aee6bb0ca Author: Marek Polacek Date: Mon Mar 30 15:49:17 2020 -0400 c++: Fix crash in gimplifier with paren init of aggregates [PR94155] Here we crash in the gimplifier because gimplify_init_ctor_eval doesn't expect null indexes for a constructor: /* ??? Here's to hoping the front end fills in all of the indices, so we don't have to figure out what's missing ourselves. */ gcc_assert (purpose); The indexes weren't filled because we never called reshape_init: for a constructor that represents parenthesized initialization of an aggregate we don't allow brace elision or designated initializers. PR c++/94155 - crash in gimplifier with paren init of aggregates. * init.c (build_vec_init): Fill in indexes. * g++.dg/cpp2a/paren-init22.C: New test.

Even simpler:
struct S { int i, j; };
struct A {
S s;
constexpr A(S e) : s(e) {}
};
void
f()
{
A g[1]({{1, 1}});
}

Reduced:
template struct A {
int i;
T t;
constexpr A(int, T e) : i(), t(e) {}
};
void
f()
{
A> g[1]({1, {1, 1}});
}
We ICE because we don't satisfy:
4662 /* ??? Here's to hoping the front end fills in all of the indices,
4663 so we don't have to figure out what's missing ourselves. */
4664 gcc_assert (purpose);

My brief attempts to reduce it to remove std::pair made the ICE go away.
