Hi,

I'm working on the intersheets references functionality and I'm
struggling with a segfault.
Until now, I didn't try to remove iref from sheets. Now, I do this with:

void SCH_EDIT_FRAME::RemoveAllIntersheetsRefs()
{
    SCH_SHEET_LIST sheets = Schematic().GetSheets();
    SCH_GLOBALLABEL* gLabel;

    m_labelTable.clear();

    for( const SCH_SHEET_PATH& sheet : sheets )
    {
        SCH_SCREEN* screen = sheet.LastScreen();

        for( SCH_ITEM* item : screen->Items() )
        {

            if( item->Type() == SCH_GLOBAL_LABEL_T )
            {
                gLabel = (SCH_GLOBALLABEL*)( item );
                SCH_IREF* iref = gLabel->GetIref();

                if( iref )
                {
                    gLabel->SetIref( nullptr );
                    gLabel->SetIrefSavedPosition( wxDefaultPosition );
                    screen->DeleteItem( iref );
                }
            }
        }
    }
}

As soon as I call DeleteItem (or RemoveFromScreen) I get a crash.
Is there something obvious I don't see ?

I still need to get familiar with screens, sheets, frames, canvas, views....

Thanks in advance.

Franck.
