This bug is just one facet of stored routines not being able to detect changes in meta-data (WL#4179). This particular problem can be triggered within a single session due to the improper management of the pre-locking list if the view is expanded after the pre-locking list is calculated. Since the overall solution for the meta-data detection issue is planned for a later release, for now a workaround is used to fix this particular aspect that only involves a single session. The workaround is to flush the thread-local stored routine cache every time a view is created or modified, causing locally cached routines to be re-evaluated upon invocation. mysql-test/r/sp-bugs.result: Add test case result for Bug#50624. mysql-test/t/sp-bugs.test: Add test case for Bug#50624. sql/sp_cache.cc: Update function description. sql/sql_view.cc: Invalidate the SP cache if a view is being created or modified.
