Hello there,

      I have some problems, when trying to work with FormEntry

      When trying 2 post string value > 16 symbols form FORM to .cgi,
      I have dlgheap.c ASSERTION, and then crash!

      All because FormEntry, when receives characters from stdin
      stream, creates sdt::string class's new instance (undocumented MakeString()), where puts
      that string!

      After this it returns this std::string object (by value)!!!
      In this moment std::string's copy constructor called.

      This copy constructor copyes pointer (not characters)!!!

      when std::string destructor runs... it tryes to free memory, by
      having pointer, BUT! memory, pointed by him is in other
      (cgicc library) heap! dbgheap.c ASSERTS that it cannot free
      memory by this pointer. Pointer MUST come from LOCAL HEAP!!!

      I hope that You will understand that I mean...
      
Best regards,
