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.
