I have a large table with many columns (480), and long column names.  When doing a mysqldump -c -uUser -pPassword, the database dump will stop right before the first insert and say "Segmentation fault".  However, if I do not specify the -c, then it correctly dumps the database.

How to repeat:
execute mysqldump -c on a database that contains a table with many (480+) columns that have long column names.

verified, see attached testcase bug10286.sql

the first table included is still within limits, the second one with one additional fields
makes mysqldump -c crash
