Minor nit:  bitset in the testcase should be qualified.

More info: This failure occurs only when the number of "machine word"
needed to represent the bitset is at most 1.  That is if you change
bitset<10> to bitset<100>, then everything should work.

Interestingly, the definition of the incriminated members of
std::_Base_bitset<1> are supplied in libstdc++-v3/src/bitset.cc.
I don't understand why the linker is not finding it.
