Praveenkumar Hulakund 79438d7506 Bug#11749556: DEBUG ASSERTION WHEN ACCESSING A VIEW AND ...

AVAILABLE MEMORY IS TOO LOW 

Analysis:
---------
In function "mysql_make_view", "table->view" is initialized
after parsing(using File_parser::parse) the view definition.
If "::parse" function fails then control is moved to label 
"err:". Here we have assert (table->view == thd->lex). 
This assert fails if "::parse" function fails, as 
table->view is not initialized yet.

File_parser::parse fails if data being parsed is incorrect/
corrupted or when memory allocation fails. In this scenario
its failing because of failure in memory allocation.

Fix:
---------
In case of failure in function "File_parser::parse", moving
to label "err:" is incorrect. Modified code to move
to label "end:".
