wxSmith, simple dialog base app and valgrind leaks

[oBFusCATed]

Hello,
I made a simple/default wxWidgets project that is dialog based. The project uses wxSmith for the GUI editing.
When I run the app through valgrind I get many leaks/possible leaks (see the log below).
Is this normal behaviour of a wx app or it is a problem of wxSmith?

[MortenMacFly]

Is this normal behaviour of a wx app or it is a problem of wxSmith?

I don't know, but try a sample provided with wxWidgets. If it's the same there, you'll know... ;-)

[Jenna]

wxWidgets is normally not used in debug-version.

Some of the objects you use are cleared automatically in the destructors of wxWidgets (as far as I know), but it might be that valgrind does not see what is freed and so beleives it's a possible leak.

[MortenMacFly]

but it might be that valgrind does not see what is freed and so beleives it's a possible leak.

Most likely. It's my experience with any code-checkers I tried with wxWidgets. Try e.g. CppCheck. It's the same there it reports literally millions of probably memory leaks whereas there aren't any (as all child objects are freed when e.g. the mother dialog is destroyed).
