Um.. sorry to ask a question not directly related to Ocaml..
I'm running Linux (Redhat 6.1) The following program
appears to leak:

#include <stdlib.h>

int main(int argc, char**argv)
{
  for(;;) {
    void *a = malloc(100);
    void *b = malloc(78);
    void *c = malloc(99);
    free(a); free(b); free(c);
  }
}

I'm baffled. This shouldn't cause fragmentation, should it?
Does anyone know of a leak in this version of Linux/glibc/malloc?
[The leak is visible by running 'free']
