Finally I solved my problem, I write this because it may help people with the
same problem.
I was using the mothod SetTextHeight after creating my texts that sets the font
size, I removed that line and program works well.
Here is a sample that causes errors :
MyFrame::MyFrame( wxWindow* parent, wxWindowID id, const wxString& title,
const wxPoint& position, const wxSize& size, long style ) :
wxFrame( parent, id, title, position, size, style )
{
a2dAggDrawer *drawer2d = new a2dAggDrawer( 0, 0 );
m_canvas = new a2dCanvas( this, wxID_ANY, wxDefaultPosition, wxDefaultSize,
wxTAB_TRAVERSAL, drawer2d);
a2dDEFAULT_CANVASFONT = new a2dFont(wxT("tahoma.ttf"), 150.0,
wxFONTENCODING_DEFAULT);
a2dCanvasDocument* root = m_canvas->GetCanvasDocument();
int maxText = 510; // crashes if you set maxText to 510.
for (int i = 0; i < maxText; ++i)
{
a2dText* text = new a2dText( wxT( "test text" ), 2*i, 2*i);
text->SetTextHeight(10); // This cause errors!
root->Append( text );
}
m_canvas->SetMappingUpp(0, 0, 1, 1);
}

Euh you mean 510 times text objects placed on the canvas? And indeed
only a problem with that font?
Anyway if all those text string use the same font and size, better
share the font between them.
a2dFont afont(wxT("tahoma.ttf"), 150.0, wxFONTENCODING_DEFAULT)
mText = new a2dText( wxT("test text."), 0, 0, afont);
mText2 = new a2dText( wxT("test text2."), 0, 100, afont);
etc.
That should start sharing the loaded font, i think.
