Bug ID: 71380
Summary: [7 Regression] internal compiler error: in
copy_cond_phi_nodes, at
graphite-isl-ast-to-gimple.c:2498
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
GCC trunk at r237026 ICEs on the testcase:
int *a;
int b, c, d, e, g;
char f;
void fn1() {
for (; c;) {
b = 0;
for (; b <= 2; b++) {
unsigned **h = (unsigned **) &a[b];
*h = (g && (e = d)) != f++;
}
}
}
