Hi Daniel and thanks for the bug report!

The creation_ctx object is not allocated directly on the heap, it is using one of
our custom memory allocators. (Stored_routine_creation_ctx inherits from
Sql_alloc which redefines new.) Objects allocated using this memory allocator
do not need to be deallocated individually, but will be deleted during
a common clean-up phase later.

Deletion can be required anyway to run destructors, but this should not be
needed in this case.
