Re: [Sbcl-help] Is it possible to "catch" C++ exceptions via sb-alien in SBCL?

[John M. <jm...@ma...>]

How should I interpret the lack of response to this question?

(0) I should not want to restart after signals/exceptions, as that
really means the C++ DLL/DSO data/stack/whatever is hopelessly screwed
up.

(1) It is not possible to restart the C++ after either a signal or
exception, as there are no mechanics in SBCL to do so.

(2) It is possible to write such mechanics, but they would be a PITA
to implement.

(3) It is a stupid question, as there is another obvious -- to
everybody but me -- solution.  (Pray tell, what might that be?)

(4) Nobody has a clue.
