Hi,
through Instruments I found a memory leak outside my code in a pqlib, the postgres client library.
This is what Leaks prints out:
Bytes Used # Leaks Symbol Name
84.81 KB 100.0% 48 PQgetResult
84.81 KB 100.0% 48 pqParseInput3
80.00 KB 94.3% 40 pqResultAlloc
80.00 KB 94.3% 40 malloc
4.00 KB 4.7% 4 pqAddTuple
4.00 KB 4.7% 4 malloc
832 Bytes 0.9% 4 PQmakeEmptyPGresult
832 Bytes 0.9% 4 malloc
I thought that inside PQgetResult there ought to be a call to pqParseInput3, inside of which I would then e.g. find a call to pqResultAlloc. But this is not the case. So I thought maybe the compiled version of the C-library I am using here does not match the sourcecode I obtained. I recompiled the library from source, built the Objective-C framework and rebuilt my app and did a new trace, but the leaks' trees were identical also now that I excluded the source for error of there being a difference in version.
Please can someone help how to read this?
Cheers
