[Bug c++/14340] New: libstdc++ debug mode: failure to convert iterator to const_iterator

["phil dot el at wanadoo dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

#include <vector>
std::vector<int>::const_iterator find_arc()
{
	std::vector<int> v;
	std::vector<int>::const_iterator it = v.begin();
	std::vector<int>::const_iterator end = v.end();
	return it == end ? v.end() : it;
}


g++ -D_GLIBCXX_DEBUG -c debug-mode-1.cpp

debug-mode-1.cpp: In function
`__gnu_debug::_Safe_iterator<__gnu_cxx::__normal_iterator<const int*,
__gnu_norm::vector<int, std::allocator<int> > >, __gnu_debug_def::vector<int,
std::allocator<int> > > find_arc()':
debug-mode-1.cpp:10: error: operands to ?: have different types

the type are vector<int>::iterator and vector<int>::const_iterator but
a conversion should occur imho.

regards,
Phil
