Even in pre, I try to avoid gratuitous changes. Before WT-27,
the ABI was pretty much in flux. Since WT-27, it's supposed to be
stable, but if there are changes needed, it will happen, and I can't
enforce that they all happen before pre1.
And if you diff pre8 and pre9, you will see that there are no
explicit ABI changes. What happen is that I changed the version of
wireless.h. In the new version, IW_ENCODING_TOKEN_MAX is larger, which
make the struct wireless_config larger. As the app pass the old
smaller version, the lib goes out of bound.
I believe one way to fix the overall problem would be to
always keep the stable version of iwlib (version 27 in our case), and
have other programs compiled against that, unless they really depend
on a feature only found in the latest version (and then, they have to
deal with the fact that it's a pre). I don't think keeping two
versions of the lib would be too difficult.
