bug#66127: 28.2; emacs crash after single C-g

[tom]

Sorry I do not have a minimal test case.

Since a long time ago, single C-g crashes emacs for me so when there is
something long running blocking emacs, it is not possible to reliably
interrupt it.

I observe this behaviour often when using the notmuch email client and
trying to display a long thread.  When notmuch block emacs for ages and
I press single C-g, sometimes I get the following crash:

Fatal error 11: Segmentation fault
