(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I tried reproducing this on the current Emacs trunk:

larsi@giant:~/src/emacs/trunk$ ./src/emacs --batch -q --eval 
'(dump-emacs-portable  "/tmp/emacs.pdmp")'
Dumping fingerprint: 
242a38e947fb351c885b84edcc58743b99c0803abfc37d2f3a62eb0ed696c781
Dump complete
Byte counts: header=100 hot=7603292 discardable=135072 cold=3591048
Reloc counts: hot=428962 discardable=5173
larsi@giant:~/src/emacs/trunk$ ./src/emacs -Q --dump-file /tmp/emacs.pdmp 

But it seems to work fine there.  Are you still seeing this issue in
recent Emacs versions?
