In principle I'd agree with Michael's suggestion to rebuild ALL deps with gcc 4.7.2. Who knows what other hidden problems pop up with a mixed build chain. In this respect the various BLAS<->arch segfaults come to mind. But it's also true that arpack is a particularly sensitive beast, on Linux as well, so I'd first try to build just that and try again. On a related note, would you share your build stuff? I'd also like to switch to 4.7.x but had no time yet (and I wanted to rebuild all dependencies anyway. I'd also like to have a first go at building a 64 bit Win version). Sharing the burden of rebuilding all can save both of us time.
