Hm... is it a clean russian instalation, or you turned it on later? I don't know what and where exactly, but it always differ if you install it in other language and later switch to russian (by "dpkg --reconfigure locales" for example). And third way - if you just turn russian in freecad. And add a little more to that - there's a number of russian encodings, now utf is used in linux by default, but may it be that ocasionly choosed something else in systems locale? Oh, and... I live not in Russia, installing linux I choose russian language, but other country, so, maybe it matters somewhere while generating codes. So, what was it? :lol:

From "Â" symbols in your error message (red one) I see that it's not russian. I don't know, in what language this letters used? Maybe wrong encoding again, or maybe in conjunction with some other encoding you installed, it transforms russian letters like that? Does log parser transforms messages somehow? Then, maybe, in my installations it generates very baaaad symbols that causes segfaults?

I have run many times into problems with freecad because of russian locale (and we've been discussing about it several times, not only in Path module). It was on Ubuntu, with freecad from daily ppa (with all default systems settings), it was on Manjaro with packages from AUR, based on Qt4 and Qt5 and my local builds to. Not enough to switch freecad to english, I have to add LANG=C in all my freecad installations. Now I am sure, that segfaults happening if something throws "translated" message to the console. Not only in this exact situation with wrong angle. Maybe something in python and the way freecad uses it? I don't know.
I cannot reproduce the segfault though. I get the error message in the report view:
I'm cooler than you, because I can 8-)

You deed it so big to make me feel shame? :lol:
Hm,
Can you post a stack trace of the segfault?
Ofcourse I can :) Here:

I never said I'm against your solution
Sorry, I used wrong word. And if you guys think that I claim on you, while reading my messages, please, it's not like that. It's just my english and my head.

Good night to you all.

Oh, stack trace... did you mean running with gdb? I will recompile freecad tomorrow with debugging and make it.

No the one you provided is good - seems to happen somewhere in qt5 on the creation of the an InputField, which explains why I don't see it, I don't have qt5. Do we have someone with Qt5 who can look into this?

I did indeed just install the russian locale with "dpkg --reconfigure locales", didn't know there are differences

This also happens in English, I must have messed up the encoding.
You deed it so big to make me feel shame? :lol:
Yeah - I gotta figure out how to downsize my screenshots ;)

No worries - no offense taken. Just wanted to make sure you know we're not ignoring you or your expertise, we're just not ready to address that issue.

mlampert, sorry, I leaded you wrong way. again.
It's not tool angle problem, it is related to tool modification.

Now on this computer, where I am experimenting, I have one tool in tool library. Drill, 10mm, angle is set to 59°. Leave it like this, don't make changes in it. Because angle is < 90°, tip compensation works when I: add Job, delete default tool, add this tool and drilling operation and check tip compensation.

Second: if I first modify tool (make angle 118° for example), close FreeCAD (to apply changes in tool library part in config file), then start FreeCAD again, open my file, remove all jobs, create new job, add this tool (without making any additional changes), and when I add drilling operation - it works. If I check tip compensation, if angle is >90° - it throws error message, no segfaults.

But!
I delete this Job and everything in it, create new Job, delete default tool, open tool library, (now important) modify tool, set angle to 120° (And it looks, that angle is not important at all, I just change it somehow), press Ok, add this tool immediately to Job, and then add drilling operation - 100% segfault on Russian locale.

Because tool in my library has 59° I always tried to change it to 118° and check how it works immediately, it always segfaulted, and didn't apply changes in tool library in config file. So everytime I started again, and it leaded me to segfaults again. That's why I thought, that 59° works, and 118° not.

How it is related to locale? I don't know. I checked konsole, it does not throw any additional messages while doing changes in the tool and adding drilling.

Hope this time I get you closer to the problem.
