Bug#526442: libperl4caml-ocaml-dev: Can't use threads with www_mechanize
Package: libperl4caml-ocaml-dev
Version: 0.9.5-2
Severity: important
Here is a simple piece of code which dies with a segfault.
--------------- main.ml ---------------
let mech = Pl_WWW_Mechanize.new_ ()
let m = Mutex.create ()
let evil_thread () =
Mutex.lock m;
mech#get "http://www.debian.org";;
Mutex.unlock m
let _ =
Mutex.lock m;
mech#agent_alias "Linux Mozilla";
mech#get "http://www.gnu.org";;
Mutex.unlock m;
let _ = Thread.create evil_thread () in
Mutex.lock m;
print_string mech#content;
Mutex.unlock m
---------------------------------------
To make the .byte :
ocamlbuild -libs unix,perl4caml,threads -cflags -I,+perl,-I,+threads -lflags \
-I,/usr/lib/ocaml/3.11.0/perl/,-I,/usr/lib/ocaml/3.11.0/threads/ main.native
same problem with the .native version
