[GiNaC-devel] Why does this program crash?

[Vladimir V. Kisil]

	Dear Jan,

	Please accept my apology, you did send a complete example and I
  have overseen that. In my opinion, the issue is not with
  the inheritance as such. Symbol x is not assumed to be a left
  value. There are GiNaC::ex for this.

  Best wishes,
  Vladimir

    JR> Dear Vladimir, realsymbol is not my derived class. See
    JR> ginac/symbol.h !

    VVK>     Yes, and as far as I am aware there is no problem with
    VVK> realsymbol in GiNaC. Furthermore, in my own project (see the
    VVK> end of the email) I have successfully derived several new
    VVK> classes following the advise from the GiNaC tutorial.

    VVK>   If you are looking for an assistance you need to provide a
