http://www.codesourcery.com/cxx-abi/...l#cxx-allocate
says that exception handling requires memory allocation:

--- snip ---
2.4.2 Allocating the Exception Object

Storage is needed for exceptions being thrown. This storage must
persist while stack is being unwound, since it will be used by the
handler, and must be thread-safe. Exception object storage will
therefore normally be allocated in the heap, although implementations
may provide an emergency buffer to support throwing bad_alloc
exceptions under low memory conditions (see Section 3.3.1).

Hope that helps,
