--- Comment #3 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2011-06-23 07:00:11 UTC --- is not that the fix in PR49483 will help also in this case? Please let me know if this is considered a bug that will be eventually fixed or a feature to be added to any sort of documentation or tutorial about "vectorization with gcc"
