[Bug target/38026] New: Miscompilation for CRIS of gfortran.dg/char_result_5.f95 with -fno-gcse

[hp at gcc dot gnu dot org]

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 -funroll-loops 
execution test
FAIL: gfortran.dg/char_result_5.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  execution test

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
FAIL: gfortran.dg/char_result_5.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test

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