A small update: I think we are decently safe, because, according to the manual, the default without -fpic is "initial-exec" and we are talking only about code belonging to libsupc++.

That's not true, people usually use libsupc++_convenience.a which is
compiled with -fpic and linked into libstdc++.so.6.

Acc! I have to reanalyze the build. Then we have a serious problem, because the attribute that you suggested is not available for all targets...

A couple of additional comments: the first one, I'm wondering whether we should add an autoconf test for the support of the "initial-exec" attribute or there are better ways to know about that (or even better ways to deal with the exception machinery issue 24025 itself...); the second, much more "theoretical", I'm wondering whether the simulated TLS could also, in principle, provide simulated "initial-exec" behavior and if not, why not...


Paolo.
