--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-11-15 16:26:15 UTC ---
due to the change in signature from erase(iterator) to erase(const_iterator)

easily fixed by using a _Base_const_iterator in
__gnu_debug::map::erase(key_type)

reduced:

#include <debug/map>

struct X { X(...); };
bool operator<(X,X);

typedef __gnu_debug::map< X, unsigned > M;

int main()
{
    M m;
    m.erase( X() );
