I'm not able to reproduce this on Emacs 25 pretest with valgrind. Is it fixed?
In GNU Emacs 25.0.94.6 (x86_64-unknown-linux-gnu, X toolkit)
of 2016-06-04 built on zony
Repository revision: 7eb3bd56d0f0410d5053ee01f4b458d868682df6
Windowing system distributor 'The X.Org Foundation', version 11.0.11803000
Configured using:
'configure --cache-file=../debug-config.cache 'CFLAGS=-Og -g3
-march=native' --enable-checking --with-x-toolkit=lucid
--without-toolkit-scroll-bars --with-gif=no --with-jpeg=no'
Note that I have to --enable-checking so that USE_VALGRIND is #defined
in alloc.c otherwise valgrind complains a lot during GC.
I do get an error at the end of dumping, "a gap between BSS and heap".
I guess valgrind makes such a gap to aid in finding errors, so it's
not possible to successfully dump when running valgrind (not something
that needs to be fixed though).

**************************************************
Warning: Your system has a gap between BSS and the
heap (55495551 bytes). This usually means that exec-shield
or something similar is in effect. The dump may
fail because of this. See the section about
exec-shield in etc/PROBLEMS for more information.
