Crash with undo (after formatting: ctr+t shortcut)

[SilvioGrosso]

Hello @little-brother

Tested on:
Windows 10 and Windows 8.1 (64 bit)
With:
sqlite-gui.1.7.6-x64-no-ciphers

These past days, I have been testing sqlite-gui and I got frequent crash when undoing (ctr+z):

Unfortunately, they are very difficult to reproduce and sometimes they do not occur at all while undoing.

After many trials and errors, I have got at least one way to always reproduce the crash :-)

It suffices to:

• launch sqlite-gui
• format your SQL code (ctr+t)
• undo this change (ctr+z):
• sqlite-gui.1.7.6-x64-no-ciphers always crahes here.

Here is a screenshot of the crash with Windows 8.1 (the same occurs on Windows 10 64 bit):

Thanks. I'll check it.
Most likely the query formatter by Ctrl + T has a bug.
