Bug #59241 invalid memory read in do_div_mod with doubly assigned variables
Fix: copy my_decimal by value, to avoid dangling pointers.
mysql-test/r/func_math.result:
New test case.
mysql-test/t/func_math.test:
New test case.
sql/item_cmpfunc.cc:
No need to call fix_buffer_pointer() anymore.
sql/item_func.cc:
Copy my_decimal by value, to avoid dangling pointers.
sql/my_decimal.h:
Implement proper copy constructor and assignment operator for my_decimal.
sql/sql_analyse.cc:
No need to call fix_buffer_pointer() anymore.
strings/decimal.c:
Remove #line directive: it messes up TAGS and it confuses gdb when debugging.
