Hi,
I solved the first part of my problem with structure like "(ddii)" and "a(iibba)". The problem was g_type_init which I initialized at the bad place. But I still have problem with structure like a(aus(uudd)(uiss)).
I already sent an explanation of my problem. But I think that with the source code may be it would be possible to better understand me.
I excuse myself to still send as much lines of code, it is so that you see the parts which are goods and those which are not.
I send you below my code with an indication on the part which creates faults.
