Philippe, libast provides both malloc replacement and a complex allocation system based on io streams, e.g.sort of stdio with disciplines on steroids where even string buffers, or lists and trees of (nested) string buffers, can be a io stream or memory buffer.
Is it really wise to modify valgrind just to intercept the custom malloc/calloc/memalign/free implementation? It sounds like an over kill and might be problematic because we would have to wait until each Linux vendor has updated to the new valgrind version.
