Thread: valgrind
Hi list,
I've Installed postgresql-9.4 using apt-get as instructed here: http://www.postgresql.org/download/linux/debian/
Also installed libpq-dev with the suggested dependencies using apt-get.
And created a small program in c. You can find it here: http://pastebin.com/bRHw3Wud
When I run the progam against valgrind I get:
==3814== Memcheck, a memory error detector

There is still reachable data. Is this a bug or have I forgotten to free something?

Is this a bug or have I forgotten to free something? I'd recommend that you do as valgrind suggests and use --leak-check=full to see where it thinks the problems are. Yours, Laurenz Albe
