fix inability to write to global in some cases

before, when we initialized a variable by copying the
initialization value, it made the internal const value
references point to a duplicate value, resulting in
a phony duplicate global value being updated instead of
the real on. now the behavior is as expected.

thanks to hoppetosse for pointing out this bug on IRC.
