--- Comment #4 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Andrew Pinski from comment #3) > This also changes with -fno-strict-aliasing ... So does that mean that csmith is producing C code with UB and so this bug isn't valid ? It might also mean that all future uses of csmith I make must have -fno-strict-aliasing.
