This assigns the result of proc_bool to procvar. The result of proc_bool is not initialised, so you are assigning a random address to procvar. > procvar; // -> access violation with FPC 3.0.4 That is expected. I don't know why it worked in FPC 2.6.4. Perhaps it had a bug and assigned the address of proc_bool to procvar, but that is not the documented behaviour for mode objfpc (it is for mode tp and delphi though).
