I cannot reproduce this on x86_64-linux with GCC 4.6, nor with GCC 4.7 (both using PPL 0.11.2 but cloog 0.15.10 as from the GCC infrastructure). So I suppose the issue might be related to the cloog version used. You mark the bug as a regression - please fill out at least one known-to-work version and the library versions used for bootstrapping it.
