[erlang-questions] when does Erlang generate a crash dump?

[Matthias Lang]

By default, Erlang generates a crash dump whenever erlang:halt/1 
is evaluated.

Is that the _only_ reason Erlang can ever generate a crash dump?

(I was playing around with kill, and noticed that killing Erlang with
a SEGV doesn't generate a crash dump, which wasn't completely
unexpected, but killing Erlang with pretty much any other signal also
leaves me without a crash dump, which got me wondering when, exactly,
Erlang produces a crash dump.)
