Summary: [10/11/12/13 Regression] ICE in
reset_sched_cycles_in_current_ebb, at
sel-sched.cc:7147
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Started with r10 between 20191110 and 20191117 (one week before pr97972),
at -O2+ and with special option -march=amdfam10 :
Testcase was derived from

$ cat z1.cc
class A {
public:
A() {
a = 1;
b = 2;
}
void show() {
__builtin_printf ("\n");
__builtin_printf ("%d %d\n", a, b);
}
int a;
int b;
};
class B {
public:
B() {
arr = new A[2];
len = 2;
}
void show() {
for (int i = 0; i < len; i++)
arr[i].show();
}
A *arr;
int len;
};
void foo (void) {
B *x = new B[2];
for (int i = 0; i < 2; i++)
x[i].show();
return;
