------- Comment #4 from rguenth at gcc dot gnu dot org 2010-01-19 10:39 -------
The issue is (verified with 4.4.0):
# VUSE <SMT.11_18>
D.1626_14 = Decode_1(D)->ActualSize;
...
# complete_24 = VDEF <complete_17>
# SMT.13_25 = VDEF <SMT.13_20>
*BufLen_3 = D.1619_8;
thus the alias information is wrong. This has been fixed for 4.4.3.
