Hello,

1) foo() does not terminate.
2) foo() eats an automatic sizeof(int) Meg each call. Never released since
no foo call ever exits.

I suspect you have about 1.5 Gig VM+RAM on this system.

The OS can't really spot pathological programs for you. I imagine it hangs
because it has noplace left to run.

Regards
Tom

Please try the following:

-------------------------------------
# include "stdio.h"

static int count = 0;
# define MAX (1024*1024)
void foo(){
char a[MAX];
int i;

printf ("%d\n", count++);

for (i = 0; i < MAX; i += 100) {
a[i] = i % 256;
}

foo();
}
int main(){
foo();
return 0;
}
-------------------------------------

after printing 375, the system stops as described in my problem report.

Jürgen
