Hello!
I've run into a bit of a problem! The following code is a very
simplified version of what I've been trying to do (allocate space
for an array in a separate function). Using gcc, the program
compiles but when run only produces "Illegal Instruction" on stderr.
However, when I remove the "void"s from int *init(void), and compile
with cc, it works fine! This is driving me crazy! Is there something
about gnu or perhaps ansi c that I don't understand?

#include <stdio.h>

int *init(void);
main() {
int *ip, i=0;
ip = init();
if (ip != (int *)0)
for (i = 0; i < 10; i++)
printf("%d\n",*(ip+i));
else
printf("calloc failed\n");
}
int *init(void) {
return (int *) calloc(10,sizeof(int));
}

(It might just be relevant). Note: this is a REALLY OLD version of GCC. -- Jim Patterson Cognos Incorporated UUCP:uunet!mitel!cunews!cognos!jimp P.O.

Anyway, following a suggestion, I deleted the #include <stdlib.h> line and declared calloc myself in the file: char *calloc(int a, unsigned int b); which then proceeded to work fine. Btw, calloc was declared in exactly this manner in <stdlib.h> (extern of course), so I'm still not quite sure what's going on here. But its obviously with the way gcc is set up on this machine, not with gcc in general. -- Cameron Shelley | "Saw, n.
