Bug #45236: large blob inserts from mysqldump fail, possible

Browse Source 
memory issue ? 
 
The mysql command line client could misinterpret some character 
sequences as commands under some circumstances. 
 
The upper limit for internal readline buffer was raised to 1 GB 
(the same as for server's max_allowed_packet) so that any input 
line is processed by add_line() as a whole rather than in 
chunks.
