Bug ID: 96611
Summary: ICE in get_or_create_cluster
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: pmatos at gcc dot gnu.org
Target Milestone: ---
On GCC tip of master from 20200814.
While static analyzing the racket source (github.com/racket/racket), it fails
on (reduced):
struct {
long a;
} * b;
void c();
int d() {
c();
c(&b->a);
return 1;
}
