Ok, this instead of getting the wrong address, wine just bails out with:
wine: failed to create the process heap. The other message still appears i=
f=20
the load address is high enough.
This is how I'm testing:
I've downloaded the August (20040813) version of wine applied the patch to=
=20
comment out the reservation of the dos area in a previous email (attached=20
again, idealy we shouldn't apply this since having the stock wine work woul=
d=20
be much better), and did a ./configure && gmake depend && gmake && gmake=20
install. I've attached my wine config file. Then I just end the=20
environmental variable you said and run wine. I'm using Diablo 2 as my tes=
t=20
app.
