It appears that this issue is no longer being worked on, so we are closing it for housekeeping purposes. If you believe the issue still exists, please open a new ticket after confirming it's present in the latest release.

I'm not been able to reproduce it yet. Getting a crash instead of memory leak:
Version: '5.7.26-29-debug-log-asan' socket: '/tmp/ps/bld/usr/local/Percona-Server-5.7.26-29-debug-Linux.x86_64/mysql-test/var/tmp/mysqld.1.sock' port: 13001 Percona Server (GPL), Release 29, Revision cfe4a4b-debug
mysqld: /tmp/ps/storage/tokudb/PerconaFT/portability/file.cc:137: void try_again_after_handling_write_error(int, size_t, ssize_t): Assertion `try_again' failed.
18:35:36 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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
Please help us make Percona Server better by reporting any
bugs at https://bugs.percona.com/key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=152
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61255 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.Thread pointer: 0x0
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...
