To verify that, I tried to run temacs under gdb, but I got
this error.

(gdb) run -batch -l loadup dump
Starting program: /usr/local/work/emacs/src/temacs -batch -l loadup dump
[Thread debugging using libthread_db enabled]

Do you know about this error?  Is this a bug of gdb?  A few
months ago, I didn't see this error on running temacs under
gdb.
