    ****************************************************************
    The application is failing inside the C++ exception handling
    code. There are a number of .eh_frame sections in the
    instrumented application that have a 4 byte zero terminator
    at the end. This is disrupting the mechanism that searches
    through .eh_frame entries.
    

Problem conclusion

  • Modified PurifyPlus to properly align .eh_frame entries.
    This prevents the linker from putting the disruptive zero
    terminators at the end of .eh_frame sections.
    

Temporary fix
