My mistake:
I set an variable to nil outside the loop and then the second time around it
was not nil and therefore not populating the hash as I expected.

My little program works one. However fails when I add a loop two run

there a way to delete objects other than setting the variable to nil?
Example...
$global_var = {}
def my_func( line)
# Uses $global_var, $global_var just accumulates objects, never letting
# go.
end
STDIN.each_line do |line|
my_func( line)
end
# Now if we use a local variable like so...
def my_func( line)
local_var = {}
# We get a fresh new hash every loop, old hash and old objects we held
# on to are garbage collected automagically every time we leave the
# scope of the variable.
end
To really debug your problem we need to see your code.
