[Bug fortran/21034] New: internal compiler error: in gfc_trans_auto_array_allocation, at fortran/trans-array.c:3036

[nicolas dot girard at nerim dot net]

Hi, 
I was in the process of translating a program written in f77 into f90 when this 
bug occurred. All I did was to add parameters to a function ; these parameters 
must correspond to the dimensions of arrays, as I want to allocate memory to 
them dynamically. 
 
I declared my arrays like: 
 
real*8,dimension(n1,n2) tab1, tab2 
 
and n1 and n2 are the two variables I added in the parameters of my function. 
 
 
"$ gfc --version" gives: 
GNU Fortran 95 (GCC 4.1.0 20050413 (experimental)) 
 
Compilation options: 
-ffixed-line-length-132 -Wall -static 
 
I'm completely stuck because of this problem, therefore if you had the 
slightest idea, even just to get round this, I'd be *much* interested... 
 
Many thanks in advance !

Could you attach the .f90 file?

Sure. 
Actually the main file is a .F file. The tgz I'm about to attach contain the 
following files: 
 
- main.F : main file 
- guess.h  params.h  pinch_complet.h  prec.h: included by the preprocessor 
- routines.h.ok : when renamed to routines.h, the program compiles fine 
- routines.h.bug: when renamed to routines.h, causes the bug to appear 
 
"$ diff routines.*" gives: 
408c408 
<         subroutine solution(n,xf,fg,h1,h2,beta,pas,tolerance,nmax,xav) 
--- 
>         subroutine solution(xf,fg,h1,h2,beta,pas,tolerance,nmax,xav) 
438c438 
<         parameter (n1=5,n2=5,ndims=10) 
--- 
>         parameter (n1=5,n2=5,n=1024,ndims=10) 
 
All I did was to add "n" as a new parameter of the solution() subroutine ; here 
the call to solution() is unchanged but adding a variable corresponding to n in 
the function call changes nothing, the bug still appears. 
 
Thanks again, 
cheers

Reduced testcase is:

$ cat pr21034.f 
        subroutine solution(n)
        implicit none
        integer n
        real dte(n)
        save
        print *, dte
        end
$ gfortran -c pr21034.f
pr21034.f: In function ‘solution’:
pr21034.f:4: internal compiler error: in gfc_trans_auto_array_allocation, at
fortran/trans-array.c:3036


Please note that if "print *,dte" is replaced by any other statement using dte
(such as "dte(:) = 0" or "call anothersub(dte)"), the bug is the same. Removing
this line, removing the "save" statement or make n a parameter lead to correct
compilation.

What about 4.0? Right now, we've been trying to keep all patches applied on both
branches. Doesn't this bug happen on 4.0 too?
