re PR libstdc++/58148 (Fails to insert iterator range into sequence container with -D_GLIBCXX_DEBUG when conversion is needed)

2013-08-30  François Dumont  <fdumont@gcc.gnu.org>

	PR libstdc++/58148
	* include/debug/functions.h (__foreign_iterator_aux4): Use
	sequence const_pointer as common type to compare pointers. Add a
	fallback overload in case pointers cannot be cast to sequence
	const_pointer.
	* testsuite/23_containers/vector/modifiers/insert/58148.cc: New.
