Description:
We've found with mysql 5.0.77 that if you create a view based on the tables in the "How to repeat" section, that dropping one of the underlying tables causes mysqld to crash when "show create table viewname" is executed:

100408  9:14:39 - 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=2147483648
read_buffer_size=10485760
max_used_connections=98
max_connections=300
threads_connected=73
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 8241152 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

thd=0x2ac155f570
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=0x4665c1b8, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x80000000285
New value of fp=0x4665b9a0 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
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at 0x22a1aa0 = show create table Calypso.MarginFloorPricingRequestView

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.

how to repeat sql creates the tables and views then executes the show create table MarginFloorPricingRequestView, which causes mysqld to crash every time on our setup

How to repeat:
Will attach sql file to repeat problem

Thank you for the report.

I can not repeat described behavior with current development sources, although bug is repeatable with version 5.0.77. So closed as "Can't repeat".
