Description:
Got a repeatable crash when doing some simple queries in a few threads:
FLUSH TABLES...
INSERT IGNORE INTO ...
REPLACE INTO ...
SELECT * FROM .. LIMIT..
Version: '5.2.3-falcon-alpha-debug' socket: '/tmp/mysql.sock' port: 3306 yes
database open failed: can't open file "/home/sbester/server/5.2/mysql-5.2.3-falcon-alpha-linux-i686/data/test.fts": No such file or directory (2)
mysqld got signal 4;
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=8388572
read_buffer_size=131072
max_used_connections=67
max_connections=151
threads_connected=67
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 336762 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...
Cannot determine thread, fp=0x4407a36c, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:

New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://dev.mysql.com/doc/mysql/en/using-stack-trace.html and follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
Number of processes running now: 0

How to repeat:
will upload standalone testcase shortly.
ran tester with parameters --host=192.168.250.2:3306 --database=test --user=root --queryfile=falcon.query --threads=65 --duration=1600 --shuffle-queries=1
Suggested fix:
don't crash
