[Caml-list] Exception marshaling

Hello,

From OCaml's manual, exception marshelling does not fully work. Would it be possible to have it works at least with the same restriction 
as closure marshalling (i.e. same binary) ?

This would be useful when using software like parmap, which at the moment does not support exception, probably for this reason.

I did the extension of parmap with exception and felt on the abbve mentioned problem. With parmap, the same binary restriction is fulfilled.

Cheers,
Christophe

That looks non-trivial to implement (for closures, there is a cache of
static code pointers; no such thing exist for exceptions). You should
add your use-case to the discussion in the relevant PR.
