bug#36716: 27.0.50; Emacs crushes in console after X session, but not in screen

bug#36716: 27.0.50; Emacs crushes in console after X session, but not in screen

[Jean Louis]

I am on Hyperbola GNU/Linux-libre system. This may be related to system
itself, but may be related to GNU Emacs. I cannot know at this point.

It is reproducible.

Here is what is happening:

1. I login in console

2. I can normally start Emacs, no problems.

3. I can start X without problems.

4. If I return back from X to console, I cannot start emacs -Q as there
   is memory access problem and I get the backtrace below.

5. However, if I open `screen` in console, then again I can start
   `emacs -Q` without problems.

6. If I exit `screen` again I get the segmentation fault.

7. If I logout and login again, then I can start `emacs -Q`

Obviously the problem is happening only after X and only in console.

If somebody can help me, as I wish to solve this.

Thank you,
Jean

Looks like some problem with GPM mouse?  What if you build Emacs
without GPM?

Can someone else who has Emacs built with GPM support reproduce this?

I did not use GPM. Now I tried while using GPM, and it crashed again.

As I said, if I run screen, then there is no crash within screen.

Let me pull latest git version, recompile without GPM and try.
