  look at http://wiki.freepascal.org/leakview
If you redirect above to a file ( set environment HEAPTRC to log=file / 
on windows setting environment requires a newer gdb, see the Lazarus

Search for those that include your code.
The ide shows how often each leak recurred "(n times)",  find the ones 
with low count
