New issue by jchook on void-packages repository

https://github.com/void-linux/void-packages/issues/29164

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  Void 5.10.19_1 x86_64 GenuineIntel uptodate rrFFF
* package:  
  skype-8.69.0.77_1

### Expected behavior

Able to make and receive calls.

Sorry I'm not sure if this is the proper place to file this issue, but it seems specific to my void machine.

### Actual behavior

Unable to make or receive calls on Skype. Seeing a segfault in the logs.

Downgrading to skype-8.67.0.96_1 resolves the issue.

```
skypeforlinux[7244]: segfault at 1500200030 ip 00007fa8548510d0 sp 00007fa84c352200 error 4 in libpthread-2.32.so[7fa85484d000+f000]

```

### Steps to reproduce the behavior

1. Launch skype
2. Attempt to start or join a call
3. See that Skype fails to join the call, with no GUI error message.

If I had to guess the problem I would guess the find/replace on a binary:

```sh
	vsed -i usr/bin/skypeforlinux -e "s;share/;lib/;g"
```

Perhaps if we started with the RPM instead of the DEB?

Also we can vaguely gesture accusatively to the upgrade QA process.

If you have a patch that fixes it (specifically, the symlink route seems very simple to follow), please PR it.

@mobinmob for awareness.

@jchook Thank you for the report. I think using the rpm as a distfile makes more sense.

Edit: Well, the rpm has binaries in /usr/share, so... I will try fixing it later today or tommorow.

It is a shellscript, not a binary ;)

Hm, thanks for trying @mobinmob. I have a hard time reproducing this issue on a fresh VM.

Somehow I got one "general protection fault", similar to this, where the call failed with a loading animation and then dumped me out to the login screen. Now calls to the VM seem to work fine lol. No idea why.

```
2021-03-05T23:00:56.12863 kern.info: [ 226.306155] traps: skypeforlinux[1437] general protection fault ip:7ffa673a0214 sp:7ffa64972ad8 error:0 in slimcore.node[7ffa64ef8000+2e3e000]
```

Here's roughly what I tried...

1. Install void base on a new VM (I used libvirt / virt-manager)
2. Boot VM and login as root
3. Install some software

```sh
xbps-install -Suy
xbps-install -Suy xorg i3 i3status dmenu alacritty void-repo-nonfree void-socklog
xbps-install -S
xbps-install skype

ln -s /etc/sv/socklog-unix /var/services/
ln -s /etc/sv/nanoklogd /var/services/
```

4. Logout and log-in as a non-root user
5. Set-up X11

```sh
echo "i3" > ~/.xinitrc
startx
```

6. Launch skype + login
7. Initiate a voice call from another account + device

I did futz around with `xbps-reconfigure` and installing intel microcode, as well as dbus... perhaps related, but I feel kinda stumped now.

Edit:

Very strangely, if I change my xinitrc (on the problematic host machine) to use `xmonad` instead of `exec xmonad` I no longer get the segfault.

@ericonr I was not able to replicate the issue. There is a PR ( https://github.com/void-linux/void-packages/pull/30917 ) for the latest verson of skype - it works for me, but anypne that wants to test is welcome ofc...

Manually upgrading the package template to `version=8.69.76.76` has the same issue, but results in a different segfault:

```

Downgrading to skype-8.67.0.96_1 resolves the issue.
