Here's an absolutely essential piece of C++ lore, a stack allocator, that will allow you to, say, allocate strings and vectors on the stack. There are 2 stack allocators I know of, here and here.

Trouble was neither of them was working with gcc-4.8, both needed fixing. Here's a fixed version of Hinant's allocator. Could there some improvement or fix still be made?

After running the above example under valgrind, it will report:

==25600== HEAP SUMMARY:
==25600== in use at exit: 0 bytes in 0 blocks
==25600== total heap usage: 0 allocs, 0 frees, 0 bytes allocated
==25600== 
==25600== All heap blocks were freed -- no leaks are possible
==25600== 
==25600== For counts of detected and suppressed errors, rerun with: -v
==25600== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2)
