Latest working copy for me was svn9677.
Any steps to reproduce this crash?
1) Open Notepad
2) Open Codeblocks with a test project and check "Display info when hovering mouse over a token in the editor" from Settings->Editor->Code completion->Code completion
3) Put the mouse cursor over a token in editor and let to apear the little pop-up with description.
4) Now click on Notepad window...
BOOM!!! :D

I think that the error was introduced in latest commits with new CC plugin.
Do you know how to catch a more complex debug message from CodeBlocks?
Can you start the C::B from debugger(I mean debug C::B under C::B), and if it crashed, you can see a full call stack about every thread.
From what I see in your call-stack
codeblocks.exe caused an Access Violation at location bc68551c Reading from location bc68551c.
Registers:

....
I can not guess any thing related to CC. :)
I think it is better you can share us a test project, so we can test it on our system.
BTW: you say "Notepad" means Editor window of C::B?
:)

I've the same problem than Vali29. I'm using SVN9744 (self compiled) over Windows XP SP3, and if you remove focus from Codeblocks when CC is showing the tip you always get a segmentation fault.
Debuging within Codeblocks or within gdb alone shows the same results: the backtrace is truncated to two (sometimes three) lines. Using gdb:
Program received signal SIGSEGV, Segmentation fault.
0x00002265 in ?? ()
(gdb) bt
#0 0x00002265 in ?? ()
#1 0x627a190d in ?? ()
#2 0x003f0450 in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Compiled with gcc 4.7.0 (MinGW) and wxWidgets 2.8.12
HTH
OK, I found some clue.
When a tooltip window is destroyed, a function will be called
In sdk\wxscintilla\src\PlatWX.cpp line 749
void Window::Destroy()
{
if (wid) {
Show(false);
GETWIN(wid)->Destroy();
}
wid = 0;
}
But later, I see that this deleted Window is still used, so some function like:
// Main window proc
LRESULT WXDLLEXPORT APIENTRY _EXPORT wxWndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
// trace all messages - useful for the debugging
#ifdef __WXDEBUG__
wxLogTrace(wxTraceMessages,
wxT("Processing %s(hWnd=%08lx, wParam=%8lx, lParam=%8lx)"),
wxGetMessageName(message), (long)hWnd, (long)wParam, lParam);
#endif // __WXDEBUG__
wxWindowMSW *wnd = wxFindWinFromHandle((WXHWND) hWnd);
// when we get the first message for the HWND we just created, we associate
// it with wxWindow stored in gs_winBeingCreated
if ( !wnd && gs_winBeingCreated )
{
wxAssociateWinWithHandle(hWnd, gs_winBeingCreated);
wnd = gs_winBeingCreated;
gs_winBeingCreated = NULL;
wnd->SetHWND((WXHWND)hWnd);
}
LRESULT rc;
if ( wnd && wxEventLoop::AllowProcessing(wnd) )
rc = wnd->MSWWindowProc(message, wParam, lParam);
else
rc = ::DefWindowProc(hWnd, message, wParam, lParam);
return rc;
}
If I remember correctly, I have see such crash issue when I debug CC. Some one has a fix patch, let's see I can find it on the forum. :)

}
}
1, if another APP was activate, the C::B will receive a "de-active" event. If currently the Tooltip is the active window, it is the window to receive such event.
2, to handle the event, CCManager try to do these
// cbEVT_APP_DEACTIVATED
void CCManager::OnDeactivateApp(CodeBlocksEvent& event)
{
DoHidePopup();
cbEditor* ed = Manager::Get()->GetEditorManager()->GetBuiltinActiveEditor();
if (ed)
{
cbStyledTextCtrl* stc = ed->GetControl();
if (stc->CallTipActive())
stc->CallTipCancel();
m_CallTipActive = wxSCI_INVALID_POSITION;
}
event.Skip();
}
3, But note the destroy happens in a member function of the wxWindow, which is:
WXLRESULT wxWindowMSW::MSWWindowProc(WXUINT message, WXWPARAM wParam, WXLPARAM lParam)
{
// did we process the message?
bool processed = false;
.....
.....
case WM_KILLFOCUS:
processed = HandleKillFocus((WXHWND)(HWND)wParam);
break;
.....

wxGetMessageName(message));
#endif // __WXDEBUG__
rc.result = MSWDefWindowProc(message, wParam, lParam);
}
return rc.result;
}
Here, HandleKillFocus() function call return false, so we have a chance to call
rc.result = MSWDefWindowProc(message, wParam, lParam);
rc.result = this->MSWDefWindowProc(message, wParam, lParam);
With the analysis of my previous post, I find a better way to solve this crash issue. I mean "Do not destroy the tip window in CCManager::OnDeactivateApp"

Unfortunately, if we do not cancel the tip window, it can become "stuck" on top of everything until Code::Blocks is reactivated.
@all: If you are experiencing this crash, please test the following patch.

Oops, my fault. I forgot to commit some local changes. ... Unfortunately, the introduction of CCManager has further destabilized this feature of Abbreviations (which was already bugged, because it required event handling to be in a specific order, which it could not control).
This code will half-fix the problem (the easy part, which was sitting on my computer and hiding the problem from me). I will try to deal with the event handling this weekend.

Good to know. Is it possible to provide a binary for Clang plugin somehow for volunteers like me to beta test? I couldn't manage to compile the plugin myself as I'm not using TDM compiler and being a 'using xxx::xxx;' guy current implementation doesn't really help me much with that.
I have successfully compiled the ClangLib plugin but always crash at clang_getInclusions when they start to parse the project.

While I am in xterm or whatever terminal that might be, and call Code::Blocks via GDB and keep event's attention to terminal, it works fine. If I run Code::Blocks inside GDB and use alt-TAB to switch to Code::Blocks' splash screen, it would work until the final GUI frame drawing on the right sidebar; that is where it breaks for some reason.
Is there a (painfully, thorough) way to debug UI layer on top of layer? I really am curious to see whether this issue is
- a Code::Blocks bug
- a wxGTK bug or
- a lib64 issue for some reason.
Cheers
