[GiNaC-devel] Subclassing symbol

[Jan Rheinländer]

Hi,

the code is practically the same as in GiNaC symbol.h and symbol.cpp
(for symbol subclasses realsymbol / possymbol).
I did try using GINAC_DECLARE_REGISTERED_CLASS(ncsymbol, symbol) etc. as
well but it makes no difference.

And I just tried: If I use GiNaC::realsymbol class instead of my own
ncsymbol class the code also crashes. So maybe its a GinaC bug?
