As far as I know, neither SELinux nor any other thing should be messing up permissions; sbrk and brk (obviously) don't look like they're randomized, and the personality() call seemed to have returned success. Bisecting using snapshot.debian.org shows this started happening between 5.31.0-1 and 5.31.0-3, and only on ia32. (My amd64 machine works fine) Is there anything else I should try?
