Description:
running the create procedure statement with many levels of nested blocks crashes with stack trace:

mysqld.exe!MYSQLparse
mysqld.exe!parse_sql
mysqld.exe!mysql_parse
mysqld.exe!dispatch_command
mysqld.exe!do_command
mysqld.exe!handle_one_connection
mysqld.exe!pthread_start
mysqld.exe!_callthreadstart
mysqld.exe!_threadstart
kernel32.dll!FlsSetValue

I think it might be related to bug #37228

another testcase causing the same crash. I got syntax errors sometimes, and mostly crashes on -debug build
