------- Comment #32 from dominiq at lps dot ens dot fr 2009-06-18 08:46 -------
With the patch in comment #31 I get:

The syntax error is fixed by replacing {!vect_hw_misalign} with { !
vect_hw_misalign }. For the 32 bit mode, the failures are consistent with:

i.e., no "unaligned" nor "peeling" found.
