(closes issue #13409)
Reported by: tomaso
Patches:
      asterisk-1.6.0-rc2-cdrmemleak.patch uploaded by tomaso (license 564)

I basically spent the day, verifying that this patch 
solves the problem, and doesn't hurt in non-problem 
cases. Why valgrind did not plainly reveal this leak
absolutely mystifies and stuns me. 

Many, many thanks to tomaso for finding and providing the fix.
