NWChem 4.7 out of memory/swap problem with GOTO 1.0 in EM64T

A simple DFT task of 480 basis functions failed due to "out of memory". All of the system memory and swap space were occupied (3GB RAM, 15GB swap and counting......) no matter what number had been set to "memory total" keyword. Switching linking BLAS library from libgoto_prescott64p-r1.00.so to MKL 7.2c solved the problem, and this task actually only require ~60MB of RAM.
