Hi,
I compiled binutils (and binutils-dev) with the upstream patch, and that
made the little test work.
Unfortunately, we came up with that test after a hunt for a crash in
ekiga. And I recompiled ptlib+opal+ekiga with my patched binutils only
to find that the crash is still there :-/
That means the patch isn't good enough... and that we don't have a small
test anymore.
Indeed. Even with the new binutils 2.21.51.20110421-4, my example
works, but ptlib still crashes.
Maintainer, is the following trace (generated with hello world example
of ptlib) enough to pin down the problem? I haven't yet succeed to
create a simple example to trigger the crash.
