FYI. I replaced the sqlite3_exec call with sqlite3_prepare_v2, sqlite3_step, sqlite3_finalize.
Same results. -----Original Message----- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org]on Behalf Of Greg Morehead Sent: Friday, June 26, 2009 4:21 PM To: General Discussion of SQLite Database Subject: Re: [sqlite] Memory leak with sqlite3_exec on qnx 6.4.1 Based on the documentation in the link you sent I should only need to call free if there was an error message. But, since there is no harm in calling sqlite3_free on a null pointer I moved it out of the if statement. It had no impact, still leaking like faucet. -----Original Message----- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org]on Behalf Of Ribeiro, Glauber Sent: Friday, June 26, 2009 4:17 PM To: General Discussion of SQLite Database Subject: Re: [sqlite] Memory leak with sqlite3_exec on qnx 6.4.1 I took only a quick look, but it seems to me that sqlite3_free is only being called if there is an error.
