I've looked around some more with GDB, and here's what I'd like you to

Run temacs under GDB, and type these commands:

    (gdb) b Fload
    (gdb) commands
    >p file
    (gdb) r -batch -l loadup

Then, whenever Fload is called, GDB will display the name of the file
that is about to be loaded.  When it shows "emacs-lisp/byte-run", type
the following commands:

    (gdb) set height 0
    (gdb) b alloc.c:4718
    (gdb) commands
    >bt 2
    (gdb) c

This will run for a while until it finishes loading byte-run, and stop
on the next call to Fload.  At that time, please copy everything that
GDB displayed until that point, and put it somewhere on the Web where
I can read it (or post here).  I will then compare with what I see on
my system.  (If possible, please do this with a 32-bit build, as my
access top a 64-bit host is sporadic.)
