When they see abort: core dumped, they just curse Emacs for losing their
work and switch to vi.
I am dubious of that speculation, because Emacs is very good at not
losing your work.
It's true
that they don't complain about it on the Emacs developer list, where you
participate, because end-user complaints usually go to the GNU/Linux
distributions first.
They have not passed these complaints on to me, at least not in recent
years.
Anyway, this is a separate issue from the question of what GCC should
do. GCC should treat multiple abort calls in whatever way is most
useful for programs that have multiple abort calls.
