           Summary: Generalisation of 8730 bug
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ilgis at num dot uni-sb dot de
                CC: gcc-bugs at gcc dot gnu dot org

Dear All,

the following bug occoured

c.c: In function `two':
c.c:6: internal compiler error: in expand_expr, at expr.c:6866

when I compile the following example:

///////////////////////////////////////////
 void three(double *A);

 void one(int N1, int N2, int M, void *data)
 {
 void two(double D[N1][N2][N2])
 { three(D[M][0]);
   return;
 }
   two(data);
   return;
 }
//////////////////////////////////////////

If I remove 3-D arrays like:

//////////////////////////////////////////
 void three(double *A);

 void one(int N1, int N2, int M, void *data)
 {
 void two(double D[N1][N2])
 { three(D[M]);
   return;
 }
   two(data);
   return;
 }
/////////////////////////////////////////////

then it is Ok.

I tested it on gcc-3.3 release.

PS: when this bug will be fixed, please check 4 and more dimensional arrays to 
avoid a new bug report from me :)

Sincerely

Ilghiz

I can confirmed it ICE in 3.0.4, mainline (20030702), 3.3.1 (20030616) and 3.2.3. GCC 
did not ICE in 2.95.3 so this is a regression.

If this is a generalization of bug 8730 then it depends on it.

Acording to Phil's regression hunter, this has been failing since at least 2000-12-31 (the 
gcc earliest he has) so something before that makes this code ICE.

Postponed until GCC 3.3.2.  Nested functions are relatively rare.

It fails in all 3.x releases and I think it is not worth while to tweak the
middle-end on a release branch for such a pathological case.

What is really funny is that this works:
 void three(double *A);

 void one(int N1, int N2, int M, void *data)
 {
 void two(double D[N1*N2*N2])
 { three(&D[M]);
   return;
 }
   two(data);
   return;
 }

Nested function are not in C99.  They are a GNU extension.  Also nested 
functions are not necessary for numerical code.  Just don't nest the 
function.  This bug is not quite so critical as you want people to 
believe.  The problem is inconvenient for some, I'm sure, but if you want 
to be safe, just follow the standard. 
(You may even find out that it speeds up your code).

Nested functions are not showstoppers, and this will be fixed in GCC 3.5, so I
have moved the target milestone.
