System: NetBSD pinky.paradox.demon.co.uk 1.5U NetBSD 1.5U (PINKY) #4: Tue Apr 17 10:23:08 BST 2001 chris@pinky.paradox.demon.co.uk:/usr/obj/kern/PINKY i386
Architecture: i386
Machine: i386
>Description:
malloc coredumps if you try to allocate 4095 MB. This is what memtester does if you use the all option. Occurs on i386 and arm32.
(memtester can be found:
http://www.qcc.sk.ca/~charlesc/software/memtester/experimental/
)
>How-To-Repeat:
The following test program core dumps (unless both my boxes have dodgey memory):
#include <stdio.h>
#include <stdlib.h>
int
main()
{
void * ptr = malloc(4293918720U);
exit(EXIT_SUCCESS);
}
