Bug Description
While testing for bug 1040735, I hit the assertion on a UNIV_DEBUG enabled binary:
=======
mysqld: /media/
16:38:30 UTC - mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Please help us make Percona Server better by reporting any
bugs at http://
key_buffer_
read_buffer_
max_used_
max_threads=10000
thread_count=53
connection_count=53
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x4605c40
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

It seemed to have hit:
DBUG_ASSERT(! is_set()); in my_eof
called from
if (!result)
my_eof(thd); in ha_show_status.
There are couple of related upstream bugs (some of them fixed)

but they are hit under different contexts.
Also, not sure if related to https:/
Raghu, Stewart -
Do you have a repeatable testcase for this?
