--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Mine. This is odd IL - we're having a PHI node copying an extern and we're
getting confused about it
pr95295-3.c:7:6: note: node 0x399c5a0 (max_nunits=16, refcnt=1)
pr95295-3.c:7:6: note: stmt 0 arr_2_I_lsm.9_41 = PHI <_4(31)>
pr95295-3.c:7:6: note: children 0x399c450
pr95295-3.c:7:6: note: node (external) 0x399c450 (max_nunits=1, refcnt=1)
pr95295-3.c:7:6: note: { _4 }
of course I never thought we'll run into this ;)
