OMG! That solution works! Except that I was making a silly 
mistake and thought that GC.alloc() prototype is similar to C's 
calloc (since it has two parameters).

I fact, after writing:

(init)
s.filedesc = cast(File*)GC.calloc(File.sizeof*1);

(open)
(*(s.filedesc)).open(*(cast(string*)arg),"w+b");

now, my file remains open and I can write inside!

(The data inside is not really what it should be, but that, at 
least, is a debugging problem, not a segfault one).

Thank you once again!
