--- Comment #12 from Joost VandeVondele <joost.vandevond...@mat.ethz.ch> ---
Since the error is recurring, I have now tried to run the self-hosting. Running
:

/data/vjoost/test/outer/install/bin/valgrind --sim-hints=enable-outer
--trace-children=yes --smc-check=all-non-file --run-libc-freeres=no
--tool=memcheck -v /data/vjoost/test/inner/install/bin/valgrind
--suppressions=/data/vjoost/toolchain-r16494/install/valgrind.supp
--max-stackframe=2168152 --error-exitcode=42 --vgdb-prefix=./inner
--core-redzone-size=1000 --tool=memcheck -v
/data/schuetto/auto_regtesting/regtests/cp2k/exe/local_valgrind/cp2k.sdbg
ethanol_both_rcut10.0_e1-1_v1-4_RSR.inp

(I.e. self-hosting with added redzone, on the our executable corresponding to a
failed run, with its arguments and parameters), I get a seemingly correct run.
The output will be attached as out.innerouter.2 . Maybe it is worthwhile to
look with expert eyes.

However, after observing in that output a warning on stack switching, I added
--max-stackframe=68009224472 (as suggested, seems a bit large;-), and that lead
to a run with some other error (Memcheck: the 'impossible' happened:  
create_MC_Chunk: shadow area is accessible).
