The program restarts some times and there is no error. Stack recovery I don't know. I think it will be ok. How can I see that? I use loadlibrary and freelibrary. There are only 3 functions/procedures calling from the program. (init_proc, loop_proc, exit_proc). The library calls back a procedure (add a key to a keybuffer) but in this procedure there is no error. I tried safeloadlibrary but the same thing. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
