Hi freddy77,



Ran valgrind and purify against ctlib_leak...no memory leaks found.  After
further investigation, the allocated memory (via ctlib_leak) is going into
the cache pool, so my memory leak must be elsewhere (not in the ctlib_leak
source code).  I'll expand my search to the rest of my source code again.



Thanks for the assistance and for pointing me to valgrind.  I've used purify,
but hadn't used valgrind before.



Cheers,

mtbrown88

Could you try to install valgring and execute a

valgrind --tool=memcheck --leak-check=yes --show-reachable=yes
--num-callers=20 ./ctlib_leak

it should report leaks and where they happen. Is better to compile
FreeTDS (at least) with debugging informations.
