This is a GCC-specific extension to C/C++; it's a shortcut for alloca(),
which does its allocation on the stack, while new and malloc() do their
allocation on the heap; alloca() blocks disappear automatically upon
returning from a function. new/malloc() blocks need to be deallocated.

What compiler are you using?

(note: I'm using quite a bit of GCC-specific features in my code, which is
usually OK on Linux and MacOSX and Cygwin, but not good elsewhere)
