Description:
Passing datadir without write permissions to mysql_install_db script will cause
server crash with following back trace:
cd mysql-6.0.9:
./scripts/mysql_install_db --basedir=. --datadir=data/
...
mysqld got signal 11 ;
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.
key_buffer_size=8384512
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=1
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 337763 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

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...

thd->query at 0x934cc38 = set storage_engine=myisam

thd->killed=NOT_KILLED
I've simplified command line that causes crash:
echo "set storage_engine=myisam" | ./bin/mysqld --bootstrap --basedir=. --datadir=/ --loose-skip-innodb
Command line above works ok in 6.0.7 but fails in 6.0.8/6.0.9
How to repeat:
cd <6.0.9 dir>
echo "set storage_engine=myisam" | ./bin/mysqld --bootstrap --basedir=. --datadir=/ --loose-skip-innodb
