ok, thanks, will try that. ----- Original Message ----- From: "Pavel Ivanov" <paiva...@gmail.com> To: "General Discussion of SQLite Database" <sqlite-users@sqlite.org> Sent: Tuesday, October 20, 2009 3:24:59 PM GMT -06:00 US/Canada Central Subject: Re: [sqlite] Crash on freeing mutex in sqlite3.c
When I say "path ... completely irrelevant" it means path doesn't cause the error and it doesn't matter at all what path you're giving - you can pass an empty path and the error will still persist. ddd or gdb or whatever debugger you use - it doesn't show you memory access errors in your program (I heard totalview can do something like that but I didn't try that). But if you run your program under valgrind it will show you those types of errors. So go ahead and do it.
