Yes, GCC bug 44199 was fixed in GCC version 4.4, etc. It of course also is fixed in all later versions; so GCC releases between 4.4 and 4.8 have the fix for PR44199 but not that for PR52828. I didn't check exactly what 4.4.x versions have the fix, etc. I always assume anyone using x.y.z uses the highest z available. I don't know if those are the only fixes you need; those are the two bugs mentioned in Nicholas' patch (that MARC link above). Segher
