Problem:
When creating a temporary field for a temporary table in create_tmp_field_from_field(), a resulting field is created as an exact copy of an original one (in Field::new_field()). However, Field_enum and Field_set contain a pointer (typelib) to memory allocated in the parent table's MEM_ROOT, which under some circumstances may be deallocated later by the time a temporary table is used.
Solution:
Override the new_field() method for Field_enum and Field_set and create a separate copy of the typelib structure in there.
include/typelib.h:
Added copy_typelib() declaration

Added a testcase for bug #24117 "server crash on a FETCH with a cursor on a table which is not in the table cache"

mysys/typelib.c:

sql/field.cc:
Create a copy of the internal 'typelib' structure when copying Field_enum of Field_set objects.
sql/field.h:
Override new_field method in Field_enum (and Field_set) to copy the typelib structure.

The problem is that the GEOMETRY NOT NULL can't automatically set
any value as a default one. We always tried to complete LOAD DATA
command even if there's not enough data in file. That doesn't work
for GEOMETRY NOT NULL. Now Field_*::reset() returns an error sign
and it's checked in mysql_load()

Field_bit::set_default() did not check the bit_len, hence used the undefined
bit_ptr, causing a crash. The patch adds a check that bit_len > 0 before
following the bit_ptr.

sql/field.cc:
Checking bit_len before following the bit_ptr, since bit_ptr has no
sensible value in the case that bit_len == 0.
sql/field.h:
Field_bit::set_default() used the bit_ptr, but it is undefined,
hence causing a crash. In reality, the hierarchy order is not correct
so added a TODO comment about refactoring.
sql/log_event.cc:
Code was manipulating bits for a FIELD_TYPE_BIT field without checking
if the bit_len was > 0, hence using an undefined bit_ptr when the
class was actually a Field_bit_as_char.

When implicitly converting string fields to numbers the
string-to-number conversion error was not sent to the client.
Added code to send the conversion error as warning.
We also need to prevent generation of warnings from the places
where val_xxx() methods are called for the sole purpose of updating
the Item::null_value flag.
To achieve that a special function is added (and called) :
update_null_value(). This function will set the no_errors flag and
will call val_xxx(). The warning generation in Field_string::val_xxx()
will use the flag when generating the conversion warnings.

Fixed a lot of wrong DBUG_PRINT() statements, some of which could cause crashes
Removed usage of %lld and %p in printf strings as these are not portable or produces different results on different systems.
