In the attachment is an example of the error. How to reproduce it:</div>
<blockquote style="margin-top: 0px; margin-bottom: 0px;">
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
Without changing any text inside the QScintilla editor, set the cursor to the beginning of the first line, press and hold the
<i><b>CTRL</b></i> key and drag the mouse to the end of the first line. After selecting a few characters, usually more than 5 or 6, the example throws a exception, something like:<br>
<div><br>
</div>
<blockquote style="margin-top: 0px; margin-bottom: 0px;"><i><span>*** Error in `/usr/bin/python3': free(): invalid next size (fast): 0x01e8d3e8 ***<br>
</span><span>Aborted</span></i></blockquote>
</div>
</blockquote>

<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
The error appears to happen when calling the <i><b>selectedText </b></i>method, while the
<i><b>CTRL </b></i>key is pressed and changing the selected text with the mouse.</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
The returned string from <i><b>selectedText </b></i>is not correct, which is visible in the console window in the example just before the exception is thrown.<br>

This error was found and reproduced in multiple editors, including: ExCo, mu-editor and meditor.<br>
Probably every editor based on QScintilla has this issue.<br>
