Correct you are...   'jot 49 1 > foo ; paste -s foo | column -t' 
works for me.  'jot 50 1 > foo ; paste -s foo | column -t' segfaults.
Oddly,  'jot 50 1 | paste -s - | column -t' doesn't work either, but 
only prints a blank line instead of segfaulting?!!?  Yet there for:

 jot 50 1 > foo ; paste -s foo > t1
 jot 50 1 | paste -s - > t2

is no difference between t1 and t2!??!

Bizzare.

This is all on i386 with 4.99.54 -current from Feb 13.

Later...
