VSCode 1.40 crash after startup with segmentation fault

[deimi]

After upgrading the VSCode Snap package to 1.40, the app crashes immediately after startup with an segmentation fault.
If I revert the snap to 1.39.2, it is working fine.

• VSCode Version:
  1.40
  Snap version 86405ea 2019-11-07
• OS Version:
  Linux Mint 19.2 Cinnamon
  Kernel 4.15.0-66-generic

Steps to Reproduce:

1. Start VSCode
2. Wait about 4 second (with/without user interaction)

Does this issue occur when all extensions are disabled?: Yes

Can you please follow the steps in https://github.com/Microsoft/vscode/wiki/Native-Crash-Issues to get at more details around the crash and attach the result here? Thanks!

@bpasero I have the same issue.
Ubuntu 19.04 x64 kernel 5.0.0-32-generic
I have tried to follow the instructions in Native-Crash-Issues, but the stack trace is not very readable:

Ok, let's wait for Deepak to comment on the crash and how to proceed.

I am experiencing this same segfault as well after the upgrade to 1.40, running Arch Linux Kernel 5.3.8

[bpasero]

Are people seeing this when running the archive'd version of VSCode too? Download: https://az764295.vo.msecnd.net/stable/86405ea23e3937316009fc27c9361deee66ffbf5/code-stable-1573064450.tar.gz

From the command line run: code --no-sandbox

Running that archive looks fine here, while the snap crashes indeed.

Dmesg also contains:
