gcc 5 copy list initialization creates undefined reference

g++ > 5.1
introduced a regression

Attached code compiled with g++ -std=c++11 test.cpp

creates:
/tmp/ccDj6FO4.o: In function `main':
test.cpp:(.text+0xc7): undefined reference to `std::shared_ptr<bool>::shared_ptr()'
collect2: error: ld returned 1 exit status

all clang++ compilers compile this code fine
