Again, do you mean here you haven't checked bdwgc "master" branch or you don't have this problem with it?

I don't know. What are the alternatives?

I think this is the expected behavior. Ignore this signal in debugger.

But the address looks too small for x64 target. Check GC_SysVGetDataStart parameters passed (compare to that in gctest).
