--- Comment #13 from Stuart Haslam <stuart.has...@linaro.org> ---
In my case the tp in the signal handler is a valid timer pool pointer, or at
least it was a short time ago, so it's stale rather than corrupted.
Commenting out the odp_shm_free() in odp_timer_pool_del() makes the crash go
away (but then so does altering the timing in many other ways so it's not
conclusive).
I suspect the problem is that the call to timer_delete() from
odp_timer_pool_del() disarms and deletes the (POSIX) timer, but it's possible a
timer has just expired and the event hasn't been delivered yet. man
timer_delete says this;
"The treatment of any pending signal generated by the deleted timer is
unspecified."
We're delivering via threads rather than signals but I assume the same applies.
