It really disappeared on trunk with the Richi's patch that does reorganization in pass manager. Anyhow, as I debugged that on GCC6 branch, it's dup of PR71351. Which still has a reproducible test-case. *** This bug has been marked as a duplicate of bug 71351 ***

This fails on me on current trunk on aarch64 as well.
The original testcase ICEs for me on the GCC 6 branch on aarch64 but not on
very latest trunk.

I have a version that fails on x86_64 w/ -O2 -floop-nest-optimize:
int ii, nv, fw;
int k2[4];
void
c8 (int *u0)
{
for (;;)
{
ii = 0;
if (ii < 1)
++ii;
for (;;)
{
int vn;
for (vn = 0; vn < 2; ++vn)
{
int mm;
for (mm = 0; mm < 4; ++mm)
k2[mm] = nv;
}
if (ii != 0)
break;
*u0 = 0;
}
fw = 0;
}
}
