Dear Jason,
1) there is most probably something wrong in the compilation of the yambo 5.0.
In order to spot the origin of the NaN can you post the report file of the GW calculation done with the 5.0?
2) I do not think that you have memory problem in your diagonalization as you are dealing with small matrixes, most probably it is related with the NaN you encounter in the GW calculation.
Best,
Daniele
