[Wine]Quick fix for jack_fst?

[Walt Ogburn]

Hi guys,

Starting a new thread because the old one got very long...

I think that the information in the wine developer's guide at these two
pages is relevant here:

http://www.winehq.com/site/docs/wine-devel/address-space
http://www.winehq.com/site/docs/wine-devel/initialization

It seems that wine_init imposes some Windows-style memory constraints, and
the big memory patch probably had some effect on this.  The result is that
allocating big things after wine_init (called by fst_init) can cause
crashes.  I don't know if this is a bug in Wine, a constraint on how winelib
applications should do things, or something else, because these memory
issues are beyond me.  If somebody more knowledgeable wants to step in
here...

A quick fix for jack_fst seems to be to pre-reserve a chunk of memory,
exactly like jack_activate does, but before wine_init gets called.  I put
the following function into jfst.c:

===

void jfst_reserve_mem (int bufsize)
{
        char buf [bufsize];
        int i;

        fprintf (stderr, "Reserving memory: base=%p, size=%d, end=%p\n",
                buf, sizeof(buf), buf+sizeof(buf));
        for (i=0; i<bufsize; i++)
        {
                buf[i] = (char) (i % 256);
        }
}


===

and then insert "jfst_reserve_mem(1000000);" into main() somewhere before
fst_init.  There is no crash, but I don't know if the console thingy works
right because its infinite knobs and buttons confuse me, and I don't think
I have jack working properly.
