It turns out I looked at the logs for yesterday...
Everything is fine.
Next code:
Outputs:
2011.12.05 22:01:28 RectLabel (EURUSD,H1) pos = {12, 176314750}
2011.12.05 22:01:28 RectLabel (EURUSD,H1) other = {123, 456}
So, initialization list didn't work, there is rubbish in the structure. Is this a bug or not?

I can't understand the deinitialisation. Why does the message "Expert unloaded from pair ..." happen twice?

This is a bug in the compiler - it didn't generate an error saying that a structure cannot be initialized this way (without copy constructor). Fixed. Thanks for the post.
Uh, no. More details came up here.
In Help it says that simple structures may be copied as variables of simple types:
{ Pos pos = {100, 100}; Pos pos1 = pos; // копи конструктор pos = pos1; // копи оператор }Then why can't it be done in the initialization list? I don't want to explicitly define constructors, so as not to lose the initialization method used above.
Not critical in principle, just want to hear the final comment.
I run the terminal with 12 windows open, it eats 325 MB of RAM.
Running the multi-currency Expert Advisor, terminal eats 990 Mb of memory. The Expert Advisor views 5-minute bars for the last 48 hours + uses "fractal" indicator. If I run only to trade on one symbol, it takes 400 Mb. Is this memory consumption normal when working with 12 symbols?

Check out the article Principles of Economical Recalculation of Indicators
I forgot to mention the fractal is a standard indicator + all calculations take place every five minutes
