Even this issue seem resolved in the build of 19/01/2019

The subdivision modifier for beveled curves also does not work.

I had some info from an other user...
From the (wip) release notes : Note however there are still some missing features in the new implementation, particularly: ... Vertex creases support (to mark vertices as sharp or semi-sharp) ... We plan to added these improvements in the 2.8 series.

Now It's works and open a new floating window with 3D editor view.

Now It's works and open a new floating window with 3D editor view.

Now work.. after restart PC and Blender.. I don't konw why, Blender in my laptop crash often.. and this make me crazy.

@Brecht Van Lommel (brecht) Thanks, now everything is ok after I changed the selection method.

@Aaron Carlisle (Blendify) Yes you got it right! But blender are years that crashes from time to time, in fact I save my work compulsively.

@Brecht Van Lommel (brecht) you're right, now I download the new of today, do not know how the hell did I go wrong, I'm sorry to have made you waste time unnecessarily I apologize strongly.

@Brecht Van Lommel (brecht) Hi, I don't use a 32bit version, below the test asked me to do, with factory settings and info.

Here the details of my system.

Here the test with the BMW model, even with this scene shows a considerable increase in the rendering time with CPU.

Hello, today I downloaded the latest version and the file caused the crash Blender, below the file generated by debugging.

It also happens to me!

Hello again, I did some tests and verified that the problem of the total drainage of resources and the block of my PC with 4 GB of RAM, occurs only when the active modifier bevel in horizontal bars, none of the other modifiers I take issue, I think the problem is very unusual, as well as being definitely caused by a failure of NPR engine optimization.

OK, I understand well the difference between ram and size, and I understand also that a very small file may generate abnormal memory consumption, but believe me when I tell you that this is an inherent problem with modifiers, and covers even groups and instances, said this today I'll do some tests on a different PC with less RAM,
This is a long period of time I use freestyle to generate 2D views and I use it daily, and I found other problems caused by other problems of various kinds.

Hello, I am not very much agree with your assessment, the attached file is only 281KB with some modifiers, and in my case locks the PC, while this sub is a rendering in Freestyle that runs in just over three minutes, and it is more 103MiB

Good morning, I wanted to add some more information.

I think you can no longer reproduce the bug that caused the block, but it happened when I tried to add the material to a curve to distinguish it. In addition I can tell you that I did the outline with a mesh that I later converted to a curve bezièr

Damn, you're right, it's just a question of scale, I was stupid, I was teaching a person and I have not seen everything, but I knew he had tried to add other curves, thanks for your response and I apologize for a fake issue, but the crash is still occurred, and certainly is due to the mix of different curves.

Hi, I tried again today but to no avail, Blender runs out of resources of my PC, the cursor does not move, nothing works not even the esc key to stop,

@Antony Riakiotakis (psy-fi) Thanks, now saves files without problems

Ok I try now and I tell what happening after.

@Antony Riakiotakis (psy-fi) Ok tomorrow, I try the new version from buildbot. thanks.
But if you have already updated the file i can build it by myself with updating of my blender-git

Ok I'm not sure if I done the correct passages, this is what i done.
Because I deleted the folder and the file build_linux CMakeCache.txt is located in that folder.
I compiled blender first, with command make only, and after I changed the value on text file CMakeCache.txt to

//No help, variable specified on the command line.
CMAKE_BUILD_TYPE:STRING=Debug

and then I recompiled blender

Ok boys after the hell of compiling Blender in debug mode and installing gdb to get the output I hope this text below can help you.

@Bastien Montagne (mont29) I'm still trying to find the ccmake file where i do the change but i'm not able to find it. I apologize but can you help me please.

@Bastien Montagne (mont29) Yes i can build Blender by myself, and yes the crash happening in both cases software or not OGL

@Campbell Barton (campbellbarton) I don't understand what you mean, but I can say what happening, when I push button save or shortcut CRTL+W Blender immediately crashes.

@Campbell Barton (campbellbarton) Great man, yes, yes now work the saving files after disabling the preview image file.

@Julian Eisel (Severin)
Yes i have tested all the advice, even the last ones, as you say, and it still crashes in both cases. But the old version I not have problem.

This is the system-info.txt that of the old version 2.73a. and it working well.

So, I tried to do some fine-tuning in the preferences OpenGL, I also tried to turn off everything that was possible, but still does not save.

@Bastien Montagne (mont29)
Hi I did as you said, but I always get the same mistakes, I remind you that the old version of Blender has no problems. I'm using is an old cpu but just to make small models, when I really require more power use another pc. but like to have blender on all my workstations.

Hi, I too have the same problem, I thought it was my fault but after compilation on multiple computers only one I have this bug. with the previous version works very well. Here is the log of the crash and the specifications of the PC.
