--- Comment #1 from Michael Kuperstein <michael.m.kuperstein at intel.com> ---
__attribute__((pure)) functions are assumed not to have any side effects. That
includes writing to memory, even if it's writing through a pointer provided as
a function argument.

Marking this function with "pure" simply doesn't make sense.
