Lemme add: there's a similar, more serious issue on 4.9-rc1. x32 processes fail not just on preadv but on apparently any startup of something linked with glibc (although at least _exit() and write() do work).
I haven't yet had the tuits to bisect or debug what's the cause. -- A MAP07 (Dead Simple) raspberry tincture recipe: 0.5l 95% alcohol, 1kg raspberries, 0.4kg sugar; put into a big jar for 1 month. Filter out and throw away the fruits (can dump them into a cake, etc), let the drink age at least 3-6 months.
