System Information
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 416.94

Blender Version
Broken: version: 2.80 (sub 60), branch: blender2.7, commit date: 2019-05-07 19:17, hash: 3dc9da3a74 (splash screen says 3d9da3a74ee)
Worked: 2.79 hash: f4dc9f9d68

Short description of error

Tryed importing a heavy .obj into blender 2.8 and it crashed 3 times.
worked on the first try on 2.79. Then i opened this file on 2.8 with no problem.

Exact steps for others to reproduce the error

The file is a stupid useless heavy export from that piece of junk called SketchUp (someone put 2 bonsai in it that has 18.000 objects as leaves, each).
Probally deleting this bonsai from the file may help importing into 2.8.

But i wonder, if 2.79 could import it, why 2.8 could't?

The .obj for testing is here : Projeto Ape 2019.obj

Warning. It will take some minutes.

You wouldn't want to give us a hint and show us the error message?

There is no message. Blender just closes.

Sometimes you can trick Blender into revealing secrets by running it from the command line.

I can import your .obj on Linux, but it looks like Blender needs over 2 Gb of memory to do so.

You might try running from the command line and looking for messages about calloc or malloc returns nil.
This is a sign of running out of memory.

I have 32 Gb of memory..
And if it refers to my GPU, I think it has 4Gb
I don't know how to use the command line.
Just wondered why 2.79 worked and 2.8 didn't..

That shoots my lack of memory theory. I got nothing...

As for using command line… http://www.letmegooglethat.com/?q=windows+command+line

Monster file imports fine for me as well, we cannot do anything else without more info…

Attempt 1, importing to 2.80, 65168825e0b0:
Huh. I can actually reproduce this. After a minute or two of waiting, blender just closes.

Attempt 2, I started importing to 2.80 and 2.7 at the same time(to save time and test both), this time from command line:
My computer has gone completely haywire, screens started flashing, desktop disappeared, and a few seconds later(not long enough for a reboot) I was greeted by my windows login screen, and all my apps are closed, and only my second monitor works. A PC reboot fixed this.

Attempt 3, importing only to 2.80 again, with command line:

Additionally, windows threw this in my face: {F7614837}
And my PC started doing some funny things for a few seconds(browser tabs and desktop icons disappearing) but recovered. This makes me think there is something memory related going on here afterall, which could help explain attempt #2.

**Attempt 4, Blender 2.7**
I actually can't seem to import this into 2.7 either. Although it's hanging at 33% instead of crashing and making my PC lose its mind. Tried multiple times, waited upwards of 5 mins.

@Mets that’s lack of available RAM (or GPU RAM, code fails to allocate needed memory). Not much to be done here, besides general optimization of Blender. but that is not a bug afaiks.

In any case, no answer from OP since over a month, more than time to archive.
