Description:
On a system where AddressSanitizer includes LeakSanitizer, e.g. recent Ubuntu:

cmake ... -DWITH_DEBUG=ON -DWITH_ASAN
...
./mtr --debug-server dd_bootstrap --big-test
...
main.dd_bootstrap                        [ fail ]
        Test ended at 2017-04-19 05:44:28

CURRENT_TEST: main.dd_bootstrap
mysqltest: At line 128: command "$MYSQLD $extra_args --datadir=$DDIR" failed with wrong error: 1
...

var/tmp/server.log then contains

2017-04-19T02:44:22.541563Z 1 [ERROR] InnoDB: Cannot continue operation.

Leaving Category non-specific, not sure if this should be considered InnoDB or test environment.

Suggested fix:
Suppress LeakSanitizer reporting when server fails to start?
