Bah, still VRP and (OVF) ... (as I suspected) Visiting PHI node: lm_5 = PHI <lm_12(14), lm_21(9)> Argument #0 (14 -> 10 executable) lm_12: [-INF, 0] Argument #1 (9 -> 10 executable) lm_21: [-INF(OVF), 0] Meeting [-INF, 0] and [-INF(OVF), 0] to VARYING Intersecting VARYING and [-INF, 0] to [-INF, 0] Found new range for lm_5: [-INF, 0] so the main issue triggering the recent endless iterations is not honoring the PHI node visiting bail-out via VARYING but using previous pass range-info to create sth else from it.
