Bug ID: 85061
Summary: ICE with __builtin_offsetof applied to static member
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-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 invalid code snippet triggers an ICE since GCC 4.0.0
(when __builtin_offsetof was introduced):
=================================================
struct A
{
static int x[2];
};
int i = __builtin_offsetof(volatile A, x[0]);
=================================================
bug.cc:6:44: internal compiler error: in fold_offsetof_1, at
c-family/c-common.c:6275
int i = __builtin_offsetof(volatile A, x[0]);
