Something like

  (gdb) break xmalloc if size > 10000
  (gdb) commands
         > bt
         > continue
         > end
  (gdb)

And similarly for xzalloc and xrealloc.

Then run Emacs as usual, and the code which allocates these large
chunks of memory will be shown in the backtraces.

Nothing.  I don't need that.
