Re: [Ocaml-lib-devel] segfault in GC when creating a DynArray of size zero

[Janne H. <ja...@hy...>]

Just for the record:

I patched my O'Caml 3.08.2 byterun/obj.c by commenting out line 107

   "if (sz == 0) return arg;"

O'Caml bootstrap went without problems and the problem with 
non-tempfixed DynArray disappeared.

ciao,
janne
