             Bug #: 55543
           Summary: diamond shaped inheritance involving strings leads to
                    crashing executables (MinGW, 32 bit)
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: martin.gieseking@uos.de


Created attachment 28837
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28837
source file to reproduce the issue

When I compile the attached code with g++, mingw32 (gcc 4.7.2), I get an
executable that crashes with the following exception:

  terminate called after throwing an instance of 'std::length_error'
    what():  basic_string::_S_create

This only happens for mingw32. A 64 bit build of the same code works correctly.
So do all 32/64 bit builds for Linux targets I've tested.

Command line:
g++ --save-temps -v -m32 inherit.cpp
