This package can be used to run OCaml packages with the check for

     

       
5
       
+
       
'naked pointers' enabled. A naked pointer is a pointer outside the OCaml heap

     

       
6
       
+
       
without a valid header, which is valid in OCaml 4.x, but forbidden in the

     

       
7
       
+
       
multicore OCaml 5.x runtime.  The nnpchecker prints warnings to standard

     

       
8
       
+
       
error with the address that contains the naked pointer, the naked pointer

     

       
9
       
+
       
and the reason why the warning was raised.

     

       
10
       
+
       
See [https://discuss.ocaml.org/t/ann-a-dynamic-checker-for-detecting-naked-pointers/5805]

     

       
11

for more details on the operation of the naked pointer checker.

By convention, the opam repository adds conflicts to OCaml packages that

     

       
14
       
+
       
violate the naked pointer rule. This means that if you install this package,

     

       
15
       
+
       
you can find the subset of packages that _are_ compatible with OCaml 5.

     

       
16
       
+
       
If you spot any violations of the nnpchecker on packages, then please consider

     

       
17
       
+
       
submitting a pull request to the ocaml/opam-repository that adds a conflict

     

       
18
       
+
       
against the violating package against this one.
