No

Hard to reproduce, steps look like
1- open C:B
2- Settings->Editor
3- "Encoding settings" tab
4- view the drop-down list of encodings but press Esc/click outside to keep the same encoding
5- "Other editor settings" tab
6- change "Highlight line under caret" tickbox
7- press OK.

I get an assertion failure with a very convenient window with the following backtrace:
ASSERT INFO:
./src/common/wincmn.cpp(1517): assert "Assert failure" failed in RemoveEventHandler(): where has the event handler gone?

I'm not sure what exactly CB was doing inside cbKeyBinder::OnKeyConfigDialogDone() ...

    Sorry about the poor formatting. I can't edit the report... here's the bt:

    Are you able to reproduce this more than once? Reliably?

      Unfortunately not. I was able to repro 2-3 times in a row when I filed the report, but not anymore. I find it strange to see cbKeyBinder in that backtrace when I wasn't in the Keyboard shortcuts menu...

    Same assert failure: http://forums.codeblocks.org/index.php/topic,22489.0.html
    This happens (not every single time but less than 10 I think) when:
    - select Settings->Editor
    - Just hit Ok. (even if you do not change anything)

    Hi,

    got the same problem when changing the syntax highlighting for markdown (got assert failure 5 times). I cannot reproduce it.

    Seems related to the number of changes I made in the foreground/background colors.

    svn 11499
    Build Sep 30 2018, 09:22:11 - wx3.1.1 (Windows , unicode) - 64 bit.

    Win 7 Professional, SP 1, i7-4790, 16 GB of RAM.

    The assert may/could possibly be wxwidget related. See ticket #795 for same/similar assert which was fixed in SVN11628.

    Someone with more wxWidget knowledge should look at ticket 795 and see if the fix in that ticket also fixes the issue in this ticket.
