Hello,
	The following program compiles and runs fine on my Decstation 5000/240
running Ultrix 4.2.

main() {
    vfork();
    pause();
}

However, from then on /bin/ps prints up the following:

$ ps
  PID TT STAT   TIME COMMAND
Segmentation fault
$

Can anyone explain this problem? Is it unique to my system, or does everyone
have this prob? (Also another problem is that sendmail gets the following
error no matter what I do, *unless* I trace it!

pid 29155 (sendmail) was killed on an unaligned access, at pc 0x40ccd8
