I am using a standard NetBSD 1.2/i386 installation to compile the
following program:

 | #include <unistd.h>
 | 
 | int
 | main(void)
 | {
 |     mktemp("/tmp/temp.XXXX");
 |     return 0;
 | }

But all I get is this:

 | simons@petium:/tmp$ gcc test.c -o test -Wall
 | simons@petium:/tmp$ ./test 
 | Bus error (core dumped)

Any idea what is happening? Am I fundamentally misunderstanding the
usage of this routine? Or is it a bug?
