Description
commit b0fd06a6f27212cee770961171439a44626d8f14 (MDEV-15670 - unit.my_atomic failed in buildbot with Signal 11 thrown) introduces an off-by-one overflow in unittest/mysys/thr_template.c.
This causes tests to fail:
$ ./unittest/mysys/m
|
y_atomic-t
|
# N CPUs: 20
|
1..5
|
# Testing my_atomic_add32 with 30 threads, 3000 iterations...
|
Bail out! Signal 4 thrown
|
# 5 tests planned, 0 failed, 0 was last executed
|
Backtrace:
Thread 1 "my_atomic-t" received signal SIGILL, Illegal instruction.
