[Linux, FPC] Memory leaks

[rchastain]

Hello!

I rewrote in Pascal several C++ examples and games: SplashKit Pascal examples

When I compile with -gh option, I see that all the programs have memory leaks. I don't know whether it comes from the library or from my programs.

Even this very simple example has a (small) memory leak.

Tested this example on Ubuntu under WSL and it's still an issue
