That is called symbol versioning and I think it is normal (although I
don't know in what cases gcc uses symbol versioning, I thought it was
only with the gnu linker).

Which libgcc_s.so.1 got loaded when you had this error? It looks like the
kind of thing that might happen if you use a recent libstdc++ with an
older libgcc_s.

Looks good (no unexpected failure).
