On x86_64-pc-linux-gnu I see it too when running the executable under valgrind.
Commenting line 12
! a = a ! This used to ICE.
the problem disappears.

Now also failing execution at -O0 on cris-elf and apparently
s390x-ibm-linux-gnu since r12-8227-g89ca0fffa48b79.

The code is clearly invalid Fortran.
module m
contains
subroutine s(inp)
character(*), intent(in) :: inp
character(:), allocatable :: a
a = a ! This used to ICE.
!
! The above is an invalid reference of an unallocated allocatable on
! the RHS.
!
a = inp
a = a ! This used to ICE too
if ((len (a) .ne. 5) .or. (a .ne. "hello")) STOP 1
a = a(2:3) ! Make sure that temporary creation is not broken.
if ((len (a) .ne. 2) .or. (a .ne. "el")) STOP 2
deallocate (a)
a = a ! This would ICE too.
!
! The above is an invalid reference of an unallocated allocatable on
! the RHS.
!
end subroutine s
end module m
use m
call s("hello")
end
You either need to remove the above two lines to get a valid program
or remove the testcase as it's testing processor dependent behavior.

How about changing it to compile-only? That would avoid interfering with its
value as a regression-test for PR20670, where it ICE'd.

I'm fine with that.

OK, I will then make that change.

Thomas,
you'd better re-read Steve's analysis.
Your patch left the first
a = a ! This used to ICE.
which is invalid at runtime. Try yourself running under valgrind.
Either remove this line too, or protect it with an if (allocated (a))

Thanks for pointing this out.
