# I wouldn't have thought the IFS environment variable should cause a # problem providing that the things that you are execving are not Bourne # Shell scripts Um, a nit, but it's transitive -- the thing you execv may execv something that eventually execv's a shell; you just don't know who's gonna use system() or popen(). e.g. whoda thought "vi" would exec "expreserve" which would would call system() to send mail. But it did. conclusion, IFS is a problem.
