Hello James, welcome to electron-phonon...

I have also had some segmentation faults of that type. Most should be 
eliminated
in 4.6.4. To be sure, when you run the debugger, could you type "up" several
times after it crashes? gdb should tell you which successive calling routines
are involved. Send me the whole list, and we should be able to tell where in 
the
code it crashes (what you gave me is too low level- it's in the library 
routine
__intel_new_memcpy). It may also be the ifc compiler - one of the buggiest on
the market (being free doesn't give them any rights).

Have fun and please report any successes and especially comparisons to
litterature. Much obliged.

Matthieu
