Previous frame inner to this frame (corrupt stack?)

:(

By the way, this happened only after the main window was gone. Probably a cleanup issue?

EDIT: I added a breakpoint at Manager::Shutdown(). The breakpoint is NOT reached before the crash.

main.cpp:1869    Hide();

And wham!

EDIT! Fixed! :) I only had to move this line AFTER all the event handlers were removed. Ta-da :D I'll commit now.

EDIT: Committed! At revision: 1752

Hmm. I'm not getting that crash. :) No crashes so far for me in 1745 or 1751.

ACTUALLY, can you try this:

Leave the Hide() call where it was.

In wxAUI/manager.cpp, change line(s) 1103/4 from this:

Code

    if (m_frame->GetEventHandler() == this)
        m_frame->PopEventHandler();

to just this:

Code

    m_frame->RemoveEventHandler(this);

And see if THAT is a fix for the problem.

Question - why? The events weren't triggered by wxAUI manager, but by wxScintilla, besides why would i have to change code that's part of the wxAUI toolkit, if my change DID fix the problem?

Edit: AH, I see now. You're right (in part), that code has to be changed. I submitted the bug to the wxAUI project, and also committed on SVN :)
