--- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-03-22 10:29:28 UTC --- Hm, not similar. We have Visiting PHI node: terminal_window_p_24 = PHI <terminal_window_p_3(8)> Argument #0 (8 -> 9 executable) terminal_window_p_3 Value: [0, 1] Found new range for terminal_window_p_24: [0, +INF(OVF)] which in the end triggers this.
