Bug ID: 67885
Summary: ICE on using parameter array in block
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fortran@t-online.de
Target Milestone: ---
Using a parameter array in a block with an inner block :
$ cat z1.f90
program p
block
real, parameter :: a(2) = 1.0
real :: x(2)
x = a
block
end block
end block
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z1.f90
internal compiler error: in gfc_process_block_locals, at
fortran/trans-decl.c:6096
Same issue when using other intrinsic types, etc.
---
Compiles without parameter attribute :
$ cat z2.f90
program p
block
real :: a(2) = 1.0
real :: x(2)
x = a
block
end block
end block
end

--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Deleting this inner block gives another error :
$ cat z5.f90
program p
block
real, parameter :: a(2) = 1.0
real :: x(2)
x = a
print *, x
end block
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z5.f90
/tmp/cckgiZhq.o: In function `p':
/home/.../z5.f90:5: undefined reference to `a.3386'
collect2: error: ld returned 1 exit status
$ gfortran z5.f90
/tmp/ccwaNc8P.o: In function `MAIN__':
z5.f90:(.text+0xe): undefined reference to `a.3385'

The a(2) appears to be optimized out. Don't know if the
code is legal because I haven't looked at standard, yet.
Changing your print statement to
if (x(1) /= 1.0) call abort
gives
% gfc6 -fdump-tree-original -c g5.f90
% cat g5.f90.003t.original
p ()
{
{
real(kind=4) x[2];
(void) __builtin_memcpy ((void *) &x, (void *) &a, 8);
if (x[0] != 1.0e+0)
{
_gfortran_abort ();
}
L.2:;
L.1:;
}
}

--- Comment #4 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Deleting the dimension from parameter a (making it scalar)
lets examples z1.f90 and z5.f90 compile and run fine.
$ cat y1.f90
program p
block
real, parameter :: a = 1.0
real :: x(2)
x = a
print *, x
block
print *, x
end block
print *, x
end block
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize y1.f90
$ a.out
1.00000000 1.00000000
1.00000000 1.00000000
1.00000000 1.00000000
---
$ cat y5.f90
program p
block
real, parameter :: a = 1.0
real :: x(2)
x = a
print *, x
end block
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize y5.f90
$ a.out
1.00000000 1.00000000
