Weird GCC error

[jesse_adkins]

I was messing around one day, and I got this error message...

///
test.c:8 error: called object 'x' is not a function.
///

From this code...

///
struct x {
int x;
};

void x(int v)
{
struct x x;
x(x.x);
}
///

I'm no expert at C, nor would I be caught with this in 'real code'. However, this one seems curious to me, since GCC doesn't give any errors about the function sharing a name with a variable and/or a struct. Am I just overreacting, or could this be a bug of some sort?

gcc 4.2.3, Ubuntu 8.04 (Hardy)

Looks correct to me as you can re-define variable names for inner blocks ({...}):


#include "stdio.h"

int main() {
int i;
for (i=0;i<3;i++) {
int i;
for (i=0;i<4;i++) {
printf("Hello from no. %i\n",i);
}
}
}

The code above execute in the same way as it would have done if the for-variable of the outer loop was "j".

Now being able to re-define (or overload? Don't know the actual correct term here) a function name with a variable just seems straight-forward to me since you define the variable x *inside* such a block.

Anyway, you should have written this in the "Programming Talk" section. ;-)
