I have a Debian 9 installation with a Debian 6 chroot jail. I am using a proprietary application which up until recently worked fine in the jail. But when I run its newer versions, it crashes in libc. I tired creating a newer Debian jail (Debian 8) but it still crashes. If I run it on native Debian 8, it works. If I import my Debian 6/8 jail in Docker, it still works.
Does anybody have any idea why the application would crash in chroot but not when running naively or when the chroot directory is imported and ran in Docker?
