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.
