I’m seeing the same thing... David From: caml-list-bounces@yquem.inria.fr [mailto:caml-list-bounces@yquem.inria.fr] On Behalf Of Reed Wilson Sent: 17 December 2008 06:53 To: caml-list@yquem.inria.fr Subject: [Caml-list] Freeze in 64-bit Windows Num module Hi guys, I have an issue with using the Num module in my Win64 OCaml compile. Whenever I try to operate on numbers that are too large it will lock up. For example, using: string_of_num (num_of_int max_int */ num_of_int max_int) causes the program to lock up with 100% CPU usage. This occurs in both native and bytecode programs, and it has happened with both my 3.10.2 and 3.11.0 compiles. The 32-bit Windows MSVS binaries on the OCaml website work, as do my 64-bit Linux and OS-X builds of 3.11.0. Before I submit this as a bug, can anyone who also has a 64-bit OCaml compile in Windows verify this? Thanks, Reed -- ç
