GCC isn't very clever about generating small binaries for embedded targets. Combining this with the code bloat from templates and heap allocator that must then also be linked into the program will make useful programs a tight squeeze in limited microcontroller program memory at the best of times. Dynamic memory management in long running programs with a small heap also invites fragmentation and spurious allocation failures.
