@RichFelker FWIW, PCH has always been broken with PaX ASLR (GCC needs a RANDMMAP exception). I have a feeling it's the same issue.1 reply 0 retweets 0 likes -

@CopperheadSec Yes, I'm aware PCH is broken. But it should just be disabled or fixed.1 reply 0 retweets 0 likes
@CopperheadSec Easy fix would be storing relative func ptrs in PCH. Clean portable fix would be storing indices into a table of func ptrs.
