There are no changes to the linuxulator in that range of revisions, but your version string is "master-n253798-8cdecdecb43-dirty", so you have some local changes. Any in the linuxulator? If not, please try installing gdb and running: # kgdb -q (kgdb) list *linux_sys_futex+0x5e1 and show the output. -- You are receiving this mail because: You are the assignee for the bug.home | help
