Aha. This is probably because of the memory debug's curl_domalloc() function.
I have this struct that I alloc:

struct memdebug {
  int size;
  char mem[1];
};

and then I return the struct->mem pointer. I bet that makes the memory 32bits
aligned which is badness. Try adding a dummy int between them:

struct memdebug {
  int size;
  int notused;
  char mem[1];
};

This problem doesn't exist when you build without memory debugging, right?
