The CP2K testcase (PR29975) fails with

> gfortran -O0 -c all.f90
all.f90: In function ‘cp2k_init’:
all.f90:360293: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

the source looks like 

      WRITE (UNIT=my_output_unit,FMT="(/,T2,A,T31,A50)")&
        "CP2K| Program compiled at",&
        ADJUSTR(compile_date(1:MIN(50,LEN(compile_date))))


with a back trace that looks like:

Yes, I actually have known about that ICE for a few hours now, and have a patch
ready (I'm now working to reduce a testcase to add with the patch). I actually
sent you a mail to warn you (to be sure you didn't spend too much time trying
to reduce it) but it came back to me. The email address I used was jv244 at
hermes.cam.ac.uk. Is the one with just "cam.ac.uk" as domain OK?

Fixed, and I can compile cp2k again with trunk gfortran. Sorry for the
regression.
