           Summary: internal compiler error: in
                    build_data_member_initialization, at
                    cp/semantics.c:5503
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: miles@gnu.org


I don't know if this is the same as the other ICEs in
build_data_member_initialization, but it's at a different line number anyway...

Compiler version is:
g++ (Debian 20101128-1) 4.6.0 20101128 (experimental) [trunk revision 167220]

Here's the un-preprocessed source (preprocessed source attached):

  #include <string>
  #include <map>

  void f (const std::string &name, const std::string &val)
  {
    std::map<const std::string, std::string>::value_type (name, val);
  }


Compiled with:

  g++-snapshot -c -std=c++0x ,oink.cc


yields:
