Instanciating dual port memory with different r/w widths

Im trying to get Quartus to infer a vhdl array of record as dual port memory with write side being a 32bit, and read side a N*32bit datawidth. To make it even more difficult, I need it to be inferred...

I think that the memory array definition is unsuitable from the start. Quartus is generally able to infer dual port rams with different port width, you'll find examples in the Quartus software handbook. Why don't you start with a known working example? Copying the record elements as "wires" to and from the memory shouldn't be a problem.
