Bug ID: 80095
Summary: [5/6/7 Regression] ICE with this pointer in NSDMI
Product: gcc
Version: unknown
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 5.1.0
(when compiled with -std=c++1y):
===========================
struct A
{
void* p = this;
};
void foo()
{
const A& a = A{};
}
===========================
bug.cc: In function 'void foo()':
bug.cc:8:18: internal compiler error: in gimplify_expr, at gimplify.c:11957
const A& a = A{};
