But indian.el was loaded already, long ago, at the point where
ucs-tables are loaded.  So I doubt that this has anything to do with
that problem, and it was fixed already anyway.

It's better to install a newer version of GDB: the backtrace code got
improved in the year that passed since that version was built.

Not yet, but I might have some ideas later.  Emacs bootstraps (with
MinGW) just fine on my XP box.  But if I run temacs inside GDB, I see
that loading ucs-tables.el causes `obtain' to be called 3 times with
these arguments:

    Breakpoint 3, obtain (address=0x192c458, size=24) at ralloc.c:255
    255       for (heap = last_heap; heap; heap = heap->prev)
    (gdb)
    Continuing.
    Loading international/ucs-tables (source)...

    Breakpoint 3, obtain (address=0x192c458, size=102512) at ralloc.c:255
    255       for (heap = last_heap; heap; heap = heap->prev)
    (gdb)
    Continuing.

    Breakpoint 3, obtain (address=0x193f458, size=102512) at ralloc.c:255
    255       for (heap = last_heap; heap; heap = heap->prev)

Then I see an error message:

   Attempt to autoload define-minor-mode while preparing to dump

And then it aborts.  So I kinda can reproduce your problem, although
it doesn't prevent bootstrapping on my system.

I will try to find out why this error message is being printed, but
note that I don't see any such message during the actual bootstrap,
only when I run temacs _after_ bootstrapping.
