I'm sure there are other places where this could be applied to as
well, however my point was that why would:

''.to_i
''.to_s.to_s.strip.to_i

those two not SEGV, but the following would?

[].to_s.to_s.strip.to_i
-e:1: [BUG] Segmentation fault
ruby 1.7.3 (2002-09-27) [i386-freebsd4]
Abort (core dumped)

My concern is that both of our patches are covering up a problem else
where.  Why does this not break with a string but it does with an
array?  ::shrug:: I don't know but it seems like a band-aid over a
problem that will show up at a later date.  Here's a non-strip version
of the bug that applies to strings:

''.strip.strip.to_i
''.delete('').delete('').to_i
''.delete('').delete('').to_f

-sc
