When running BOINC under any of the 4.9 kernel, several projects tasks
terminate immediately in error with messages like this:
process got signal 11
SIGSEGV: segmentation violation
(example above is from WorldCommunityGrid)
Returning to 4.8 kernel allows the sames tasks to run fine.
Any idea what changes 4.9 introduces that breaks this ?

Show a backtrace, either from running in gdb or enable coredumps and
print them from one.

This is the vdso address.
According to this commit, it probably broke due to
CONFIG_LEGACY_VSYSCALL_NONE=y:

Nice find!
if I understand correctly:
- either programs need to be update/recompiled to no longer use the
old vsyscall
- either kernel has to be compile with
option CONFIG_LEGACY_VSYSCALL_EMULATE=y
