[AMBER-Developers] potential optimisation problem in qm2_get_qm_forces

Again, compiling with ifort -check, I get a complaint from the qm/mm
parts of the code:

ifort -check -c -ip -O3 -xHost -axSSE4.1,SSSE3 -FR -o
qm2_get_qm_forces.o _qm2_get_qm_forces.f
Space exceeded in Data Dependence Test in _qm2_deriv_qm_analyt_
Subdivide routine into smaller ones to avoid optimization loss
An internal threshold was exceeded for routine _qm2_deriv_qm_analyt_
and optimization level may be reduced. See HTTP://SOFTWARE.INTEL.COM/EN-US/ARTICLES/INTERNAL-THRESHOLD-WAS-EXCEEDED
  for more information and advice.

Does this represent a problem (even if just at the efficiency level)?

Cheers,
Ben
