$ gcc -O3 -fstack-protector-strong -fopenmp -ffast-math

This is the minimal cmdline to trigger the issue I could find.
cat testcase.i

int width

for (int slice; slice < b; slice++) {
for (int i; i < b->width; i++) {
dt_aligned_pixel_t contrib;
for (int k = 0; k < 4; k++)
buf[offsets[k]] += contrib[k];
}
float *dest, *src = oy;
for (int i = 0; i < oy; i++)
dest[i] += src[i];
}
