Bug ID: 79363
Summary: [6/7 Regression] ICE with NSDMI and array
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
Target Milestone: ---
The following valid code snippet triggers an ICE since GCC 6.1.0:
==================
struct A {};
struct B
{
B() {}
int i;
A a[]{};
};
==================
bug.cc: In constructor 'B::B()':
bug.cc:5:7: internal compiler error: tree check: expected tree that contains
'common' structure, have 'constructor' in perform_member_init, at cp/init.c:725
B() {}
