Crusher: Work around tcmalloc issue.

cee/15.0.0 with GPU MPI buffers can crash in a system lib like this:

#4  0x00007fffe159e35b in (anonymous namespace)::do_free_with_callback(void*, void (*)(void*)) [clone .constprop.0] () from /opt/cray/pe/cce/15.0.0/cce/x86_64/lib/libtcmalloc_minimal.so.1

#13 0x00007fffffff42e7 in ?? ()
#14 0x0000000000000000 in ?? ()

Work around this by using cee/14.0.3.
