             Bug #: 54144
           Summary: With -sdt=c++0x certain incorrect arguments to
                    map.insert cause gcc crash
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: im_also_greg@yahoo.com

Preprocessor output

This incorrect code causes gcc to crash with a message ending:

...
/usr/include/c++/4.6/bits/stl_tree.h:1335: confused by earlier errors, bailing
out

(full message pasted below)


#include <map>
#include <iostream>

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

  std::map <std::string,std::string> a_map;
  a_map.insert("Hello","Hi");

}

Built with:
g++ -D__STDC_LIMIT_MACROS -std=c++0x -o test test2.cpp

System is:  i386 Ubuntu 12.04.  g++ pre-built in package build-essential. 
gcc4.4 package is also installed on this machine.

Fixing the code is the work-around of course.  Just submitting this (my first
ever) bug report in case it is useful.  

Preprocessor output is attached.

Full error message:
