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...
stack_bottom = 0 thread_stack 0x40000
/usr/local/mysql/bin/mysqld(my_print_stacktrace+0x35)[0x7a99d5]
/usr/local/mysql/bin/mysqld(handle_fatal_signal+0x4a4)[0x684974]
/lib64/libpthread.so.0(+0xf7e0)[0x7fd53c0237e0]
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

Installation of system tables failed!  Examine the logs in
/usr/local/mysql/var for more information.

You can try to start the mysqld daemon with:

    shell> /usr/local/mysql/bin/mysqld --skip-grant &

and use the command line tool /usr/local/mysql/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /usr/local/mysql/bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /usr/local/mysql/var that may be helpful.

Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
describes problems on your OS.  Another information source are the
MySQL email archives available at http://lists.mysql.com/.

Please check all of the above before submitting a bug report

This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !

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=1073741824
read_buffer_size=16777216
max_used_connections=0
max_threads=500
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 17438353 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
