Description:
Statement SHOW CREATE TRIGGER any_string invoked from any client with any priviledges causes server crash 

The same operation with 5.0.37-community just generates an error.

How to repeat:
mysql>SHOW CREATE TRIGGER a;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Thank you for a bug report. Verified just as described. 5.1.21 had the same behaviour, but 5.0.x, indeed, just give error message (as this statement was added in MySQL 5.1.21.)

  SHOW CREATE TRIGGER was not checking for detected errors 
  opening/reading the trigger filer. 
  Fixed to return the already generated error.
