The subject says it. I have spent a considerable time debugging this until I found this report. The latest patch by Andreas (although it did not apply cleanly) fixed the issue. Here are my observations:
I use arpack from a C++ program via some selfmade bindings. Without the patch it works fine on an amd 64bit machine using gcc/gfortran 4.0.1 (SuSE 10.0). I get lots of nans in znaupd on two amd 32bit machines: One running SuSE 9.2 using gcc/g77 3.3, and the other one running Debian etch using gfortran/gcc 4.1. arpack was self compiled on the SuSE machines (using the debian source packages - a procedure I often use successfully for scientific software that is not available on SuSE, thanks to the good suppport in Debian) and I used the .deb on the debian machine.
