Hi everybody,
I have a strange bug only on Linux. 
When I create a t_symbol with @ inside it and try to add it to a binbuf PD crashes .

dummy code that crashes:

t_gotfn mpreset = zgetfn(&y->g_pd, s_preset);
SETSYMBOL(av, gensym("@zaza"));
binbuf_add(b, 1, av);
mpreset(y, b); (it seems to crash here)

dummy code that works:

t_gotfn mpreset = zgetfn(&y->g_pd, s_preset);
SETSYMBOL(av, gensym("zaza"));
binbuf_add(b, 1, av);
mpreset(y, b);

I don't know if it's a linking problem or if I do something wrong in the code. Any help will be welcome !

Here the link of the full project : https://github.com/CICM/CicmWrapper
In the CreamLibrary folder, you can use the codeblock project "c.library" if you want to try it. And the bug is in the function "preset_store" of the file "c.preset.cpp" in the chocolate subfolder. 

Cheers
