Bug ID: 83713
Summary: [6/7/8 Regression] ICE in do_narrow at
gcc/convert.c:474
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: marxin at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
Target Milestone: ---
Starting from r246756 we ICE on:
$ cat Buffer.ii
class a
{
char b;
void c ();
};
void
a::c ()
{
&b + ((long long) &b & 0);
}
$ g++ Buffer.ii -O2 -m32 -c
Buffer.ii: In member function ‘void a::c()’:
Buffer.ii:9:27: internal compiler error: tree check: expected boolean_type or
enumeral_type or integer_type, have pointer_type in do_narrow, at convert.c:474
&b + ((long long) &b & 0);
