Using Code::Blocks / crash when I try to open a wxsmith file under C::B against wx 3.3.1

« Last post by ollydbg on January 23, 2026, 01:52:47 pm »

Hi, when I try to open a wxsmith file in my built C::B against wx 3.3.1, I see a crash, here is the crash call stack:

Thanks for testing. If this works then I will leave wxsresourcetree as is, because the change would be complex.

Probably works because wxsresourcetree uses cbLoadBitmap(), which calls wxImage::LoadFile() instead of wxBitmap::LoadFile().

I reverted the patch that was posted here above yesterday,and used your latest commit.

CB now starts up for me without problems (or at least not directly visible to me ;-) )

The change is not finished, wxsresourcetree must be modified.

When I experimented with this, my friends loved discovering our unique creations together! Any tips on level design?

I have just commited r13775 implementing delay-load of most images. This commit will make easier changing to SVG in the near future.

wxsresourcetree must still be modified before checking if C::B still hangs at startup.

not sure if really usable

It is very helpful indeed.

IMHO the problem is wxSmith uses global objects to register items:

Code

namespace
{
    wxsRegisterItem<wxsAnimationCtrl> Reg(_T("AnimationCtrl"),wxsTWidget,_T("Standard"),370);

The constructor of wxsRegisterItem (in wxsitemfactory.h:200) calls wxBitmap::LoadFile(), but this call will happen before the image handlers have been initialized because global objects are constructed before program starts.

Code

            wxString DataPath = ConfigManager::GetDataFolder() + _T("/images/wxsmith/");
            Info.Icon32.LoadFile(DataPath+Info.ClassName+_T("32.png"),wxBITMAP_TYPE_PNG);
            Info.Icon16.LoadFile(DataPath+Info.ClassName+_T("16.png"),wxBITMAP_TYPE_PNG);

One possible solution would be delay loading the icons, i.e. load them the first time they are needed.

not sure if really usable, can not reproduce, ran in gdb, when it hang : ctrl-c and then bt.
but most of the other times I get something else ...
