Are you sure, the expression is indeed globally static?
From my experience [1], Xilinx warns you about violating the VHDL
standard (by the way, what version do you use?), though such standard's
constraints are really artificial and have been overcome many years ago
by proprietary vendors such as Xilinx and Altera, but unfortunately not
GHDL. At least the issue I've encountered could be easy fixed in
another VHDL simulator [2].
