11412,reserve() : null pointer passed to memmove,Alexandre Hamez <alexandre.hamez@…>,Ion Gaztañaga,"The following error is reported 
{{{
boost/container/detail/copy_move_algo.hpp:199:4: runtime error: null pointer passed as argument 2, which is declared to never be null
}}}

when compiling the following example with GCC 5 with the {{{-fsanitize=undefined}}} option

{{{
#include <boost/container/flat_set.hpp>

int main ()
{
  boost::container::flat_set<unsigned int> fs;
  fs.reserve(10);
  return 0;
}
}}}

Indeed, when putting a breakpoint at the reported line, the {{{f}}} argument is null.

{{{
std::memmove((iterator_to_raw_pointer)(r), (iterator_to_raw_pointer)(f), sizeof(value_type)*n);
}}}

However, valgrind does not report anything and calling {{{capacity()}}} reports the correct size.",Bugs,closed,To Be Determined,container,Boost 1.58.0,Problem,fixed,,
