Original bug ID: 4476
Reporter: gerd
Assigned to: @damiendoligez
Status: closed (set by @damiendoligez on 2010-05-12T15:15:23Z)
Resolution: fixed
Priority: normal
Severity: minor
Version: 3.10.0
Fixed in version: 3.11.0
Category: ~DO NOT USE (was: OCaml general)
Related to: #3214

Bug description

In native code, Invalid_argument exceptions thrown by illegal array accesses cannot be fully printed by Printexc.to_string. Here is a test program:

let e = try [| |].(0); raise Not_found with e -> e;;
let e' = Invalid_argument "foo";;
print_endline (Printexc.to_string e);;
print_endline (Printexc.to_string e');;

This prints:
Invalid_argument(_)
Invalid_argument("foo")

In bytecode, everything is correct.

Additional information

Maybe related to #3214.

Too dangerous to fix for 3.10.2 after all.
Will be fixed in 3.11.
