А где патч? :)

Поскольку это будет одна из болячек для p9, поставлю-ка блокер. 2 lav: в сизиф отправлена сборка 2.40.1-alt2 без -ffast-math; спасибо. 2 ldv: проверь, как будет удобно, я уж засыпаю...
На тривиальных примерах, которые я здесь приводил, разницы больше нет.
Спасибо; тогда считаю вопрос закрытым.
