      Description

      If I run mysqld with the following command line

      sql/mysqld --defaults-file=/scratch/db/maria-container/maria-test.my.cnf --datadir=/scratch/db/maria-container/maria-test/data --lc-messages-dir=/scratch/develop/maria/bzr/maria-oqgraph-maintenance/build/sql/share --plugin-dir=`pwd`/storage/oqgraph -#d,oq-debug,info
      

      and I have a misconfigured entry for pid-file in my defaults file, such that the path is unwritable, I get a segfault when mysqld attempts to report the fact

      Program received signal SIGSEGV, Segmentation fault.
