12404,undefined behaviour in interval container library,Hannu Rummukainen <hannu.rummukainen@…>,Joachim Faulhaber,The file boost/icl/interval_bounds.hpp (line 45) contains the expression ((~_bits<<1) & _left) which invokes undefined behaviour by left shifting a negative signed integer. It can be fixed by replacing the expression with (((bound_type)~_bits<<1) & _left).  This issue was detected by GCC 6.1.0 with -fsanitize=undefined.,Bugs,closed,To Be Determined,ICL,Boost 1.61.0,Problem,fixed,,Joachim Faulhaber
