[Bug c++/14176] New: standard allocator crashes when deallocating segment of zero length.

["nivelle at mpi-sb dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hello,

I am not certain what the standard says about this, but the following code
causes a segmentation fault under various versions of g++ .
It is a bit strange off course to allocate segments of length 0, but
for symmetry it makes sense to allow it.

yours,
Hans.


#include <memory>

int main( int argc, char * argv[] )
{

   unsigned int len = 0;

   std::allocator< int > a;
   int* p = a. allocate( len );
   a. deallocate( p, len );

};
