bug#47774: 28.0.50; crash when using minibuffer

[Vincenzo Pupillo]

The crash occur when switching from one buffer to others using
counsel-switch-buffer (via minibuffer). I'm wasn't doing anything special, in *scratch* buffer
I was trying to figure out how to properly use fontset functions.

Could you provide a backtrace?  See `C-h C-d' for information on how to
do that.

Could you provide a recipe for reproducing it, starting from "emacs -Q"?

Please show a recipe to reproduce this, preferably starting from
"emacs -Q".  And if by "crash" you mean Emacs dumps core, please run
it under GDB and show a C-level backtrace from the crash.

Thanks.

[Vincenzo Pupillo]

Sorry, I forgot to attach the stack trace (emacs crashed even during my first bug report :-(, the stack trace is the same). 
No problem with emacs 27.2 . Now I'm trying to reproduce the bug with emacs -Q.

After a day of use, I can confirm: after setting (setq x-gtk-use-system-tooltips t) no crash happens.
