To repeat, run gfortran.dg/char_result_5.f95 from th 4.3-branch with -fno-gcse.
In the gcc objdir:
make check-fortran 'RUNTESTFLAGS=--target_board=cris-sim/-fno-gcse
dg.exp=char_result_5.f90'
Observe:
Using /tmp/hpautotest-gcc43/gcc/gcc/testsuite/config/default.exp as
tool-and-target-specific interface file.
Running /tmp/hpautotest-gcc43/gcc/gcc/testsuite/gfortran.dg/dg.exp ...

FAIL: gfortran.dg/char_result_5.f90 -O3 -fomit-frame-pointer

with gfortran.log saying for both FAILs:
PASS: gfortran.dg/char_result_5.f90 -O3 -fomit-frame-pointer -funroll-loops
(test for excess errors)
Operating system error: Illegal seek^M
Memory allocation failed^M

I'm guessing a target-bug, exposed by -fno-gcse.
