Notepad3 v5.19.815.2595 crashes while opening the file

[ArturSprinter]

When opening a file (from command line or in notepad menus) application tries to load file for some time (few seconds) and than crashes and closes immediately leaving no information.

After opening the file I recognized the scrollbar appears, indicating the file content had to be loaded or analyzed for it's length.

Error happens when I try to open Apache config file: _httpd.conf_

Here is my configuration:

I attached Windows report file, but it doesn't tell to much.

I decided to use Notepad3 after many years of using Notepad2, but now I cannot work normally (without thinking if I can open file, instead of just editing the file).

This is a big step back in comparison to reliable Notepad2 😔

@ArturSprinter : Sorry for the inconvenience.
I am not able to reproduce your issue (using your configuration and same NP3 version).
If possible, please provide an (anonymous, non sensitive data) example file, which crashes NP3.
Ed.: ... meanwhile I found an example ... debugging ...

[RaiKoHoff]

While analyzing the problem, feel free to to test latest development beta version, e.g. Notepad3Portable_5.19.919.2643_BETA (seems, that this version does not have a problem with my testfile).
(For beta channel access see: #1129)

I have problem opening this file (I changed extension to _.txt_ because GitHub doesn't support _.conf_ extension for attachments):
httpd.conf.txt

My machine spec:

• OS: Windows 10 Pro v1903 (build 18326.295) x64
• CPU: Intel Core i3-8100
• RAM: 8GB DDR3

Maybe later I will download your repository and check what causes problem on my machine.

[RaiKoHoff]

Okay, the problem is [Settings] IndentWidth=0 , Menu-Settings->Tab Settings... : Indentation size: 0,
causing a "division by zero" exception, which crashes the last release version. This has been fixed in the current beta versions.
Workaround for release version is to set a value != 0 ... - sorry for the inconvenience.

[ArturSprinter]

Ok. Good to know 😉

With Notepad2 this setting value worked without causing any problems (I cloned my Notepad2 settings, to have the same feel with new Notepad3).

[RaiKoHoff]

Yes, in Notepad3 beside new features, a lot of already existing Notepad2 functions have been adapted/extended or reworked, so some "bugs" may have been added too. Unfortunately, we only have a manual regression testing :cry:, which leaves a lot of space for bugs to slip into the code ...
