Subject: [Caml-list] Unison compiled with OCaml 4.00.0 allocates huge amount
 of memory, fails


Just had this bug reported against Fedora:

  https://bugzilla.redhat.com/show_bug.cgi?id=877128

where Unison dies allocating a huge amount of memory:

mmap(NULL, 259407338535944192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)

It seems similar (but is probably not related) to the old bug in 3.10
where it would allocate 34 GB of RAM on a 64 bit machine
(https://bugzilla.redhat.com/show_bug.cgi?id=446940).

Has anyone seen anything like this in OCaml 4.00.[01]?

Rich.
