Bug ID: 79796
Summary: [5/6/7 Regression] ICE with NSDMI and this pointer
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 (compiled with -std=c++1y) triggers
an ICE since GCC 5.1.0:
=====================
struct A
{
A* p = this;
};
void foo()
{
A a;
a = A({});
}
=====================
bug.cc: In function 'void foo()':
bug.cc:9:5: internal compiler error: in gimplify_expr, at gimplify.c:11950
a = A({});
