--- Comment #6 from janus at gcc dot gnu.org 2012-07-20 21:47:43 UTC --- (In reply to comment #4) > Janus, please try to run the executable under valgrind: Sorry, I still can not reproduce it. Neither with valgrind, nor at later revisions (189690,189711). Did you use any other flags except "-O3 -ffast-math" which you did not tell us?
