While it is a wrong-code bug, I doubt many people are using
-O -fcrossjumping
options together, and -fcrossjumping is only the default for -O2+,
where live problem is added by default.

Please look at http://gcc.gnu.org/
us, I believe we aren't exporting new _ZTS* symbols for some time, only
_ZTI*, right?
I'll try to post updated abilist files for
i686/x86_64/powerpc{,64}/s390{,x}-linux once this is resolved.
So here is a patch to fix that up. Ok for trunk/4.6?
