First: are you planning to use the divcon capability? If not, you can
probably wait as this problem is looked into. We are currently evaluating
some proposed fixes that look like optimization problems with some versions of
ifort (see the next item).
Second: what does "ifort -V" say? Sander is a fortran program, so the C/C++
flags are not relevant here.
Third: if you need divcon running on the ia64, you could try lowering the
optimization level by chaning the FOPTFLAGS variable in
amber9/src/dcqtp/mod/Makefile, and recompiling.

This seems weird, since a segfault should end the job. Do you see this
behaviour if you run test by hand, or only when it is invoked by the Makefile?
