I had a further look into this. It is sufficient to compile the file mc_moves.F
without graphite to avoid the segfault, while compiling it with '-fgraphite
-fgraphite-identity' is enough to get the segfault. I would therefore guess
this is unrelated to blocking and local to the file mc_moves.F. I'll see if I
can narrow down the problem to the single subroutine (change_bond_length) which
I suspect is the issue. [all of this with trunk 143207]
