hi, i am using zeos with bcb6 and a sqlite db. i am searching for memory leaks with codeguard shipped with bcb6. its not the best for it, but it is already here. however, codeguard reports many leaks by zeos in the following code lines. these two lines are reported many many times. don't know if these reports are correct, but they appear. if someone has another tool to find leaks i can test it if the leak is still present, freeware would be nice too.

i searched and found memproof, freeware, to test memory leaks. its an old tool, but it shows the same leaks.
